This updates systemd to version v249.4 from version v247.6.
Besides the many new features that can be found in the upstream
repository they also introduced a bunch of cleanup which ended up
requiring a few more patches on our side.
a) 0022-core-Handle-lookup-paths-being-symlinks.patch:
The way symlinked units were handled was changed in such that the last
name of a unit file within one of the unit directories
(/run/systemd/system, /etc/systemd/system, ...) is used as the name
for the unit. Unfortunately that code didn't take into account that
the unit directories themselves could already be symlinks and thus
caused all our units to be recognized slightly different.
There is an upstream PR for this new patch:
https://github.com/systemd/systemd/pull/20479
b) The way the APIVFS is setup has been changed in such a way that we
now always have /run. This required a few changes to the
confinement tests which did assert that they didn't exist. Instead of
adding another patch we can just adopt the upstream behavior. An
empty /run doesn't seem harmful.
As part of this work I refactored the confinement test just a little
bit to allow better debugging of test failures. Previously it would
just fail at some point and it wasn't obvious which of the many
commands failed or what the unexpected string was. This should now be
more obvious.
c) Again related to the confinement tests the way a file was tested for
being accessible was optimized. Previously systemd would in some
situations open a file twice during that check. This was reduced to
one operation but required the procfs to be mounted in a units
namespace.
An upstream bug was filed and fixed. We are now carrying the
essential patch to fix that issue until it is backported to a new
release (likely only version 250). The good part about this story is
that upstream systemd now has a test case that looks very similar to
one of our confinement tests. Hopefully that will lead to less
friction in the long run.

d) Previously we could grep for dlopen( somewhat reliably but now
upstream started using a wrapper around dlopen that is most of the
time used with linebreaks. This makes using grep not ergonomic
anymore.
With this bump we are grepping for anything that looks like a
dynamic library name (in contrast to a dlopen(3) call) and replace
those instead. That seems more robust. Time will tell if this holds.
I tried using coccinelle to patch all those call sites using its
tooling but unfornately it does stumble upon the _cleanup_
annotations that are very common in the systemd code.
e) We now have some machinery for libbpf support in our systemd build.
That being said it doesn't actually work as generating some skeletons
doesn't work just yet. It fails with the below error message and is
disabled by default (in both minimal and the regular build).

f) We do now have support for TPM2 based disk encryption in our
systemd build. The actual bits and pieces to make use of that are
missing but there are various ongoing efforts in that direction.
There is also the story about systemd in our initrd to enable this
being used for root volumes. None of this will yet work out of the
box but we can start improving on that front.
g) FIDO2 support was added systemd and consequently we can now use
that. Just with TPM2 there hasn't been any integration work with
NixOS and instead this just adds that capability to work on that.

I currently do not have much time to work on nixpkgs. Remove
myself as a maintainer from a bunch of packages to avoid that
people are waiting on me for a review.
These are all packages that I stopped using and hence just create noise
in my inbox for each change affecting them and let's face it, while I
still enjoy contributing to nixpkgs, it doesn't really make sense to be
listed there if I can't do much anyways.
Each of these packages can be taken over by someone or removed if
people think that's reasonable.
Of course, if other maintainers face issues, I can answer some questions
if needed & possible.
This doesn't work anymore and thus breaks the installation leaving a
broken `/var/lib/nextcloud`.
It isn't a big deal since we set this value in the override config
before, so the correct table-prefix is still used. In order to confirm
that, I decided to add a custom prefix to the basic test.
twisted is used in matrix-synapse for smtp handling.
Mostly this is used for password resets, but also notifications
are delivered that way.
older versions of twisted require the e-mail server to
have TLS1.0 enabled.
Obviously, quite a lot of servers have this disabled which means
synapse won't be able to deliver mails using such servers.

Deluge 1.x requires Python 2 which upstream has end-of-lifed. Deluge depends
on pythonPackages.twisted, Python 2 support for which upstream has
nowdropped. If pythonPackages.twisted is upgraded then Deluge 1.x breaks.
So, remove it instead of leaving it broken.
Deluge 2.x (deluge-2_x) is available and continues to work.
Perform the tests on the package that the `tests` attribute is a child
of, i.e. if `discourseAllPlugins.tests` is built, the tests will run
with the `discourseAllPlugins` package, not the `discourse` package as
previously.
The problem behind this is that the hardened patchset[1]. Quite recently
this led to a weird problem when Linux 5.12 was dropped (and thus had to
be removed from `nixpkgs`), there were no patches for 5.13, so
`linuxPackages_hardened_latest` had to be downgraded to 5.10 as base[2]
which may be rather unintuitive and unexpected.
To avoid these kind of "silent downgrades" in the future, it makes sense
to drop the attribute entirely. If somebody wants to use a hardened
kernel, it's better to explicitly pin it using the newly introduced
versioned attributes, e.g. `linuxPackages_4_14_hardened`.
