nixos/switch-to-configuration: add new implementation
This adds an implementation of switch-to-configuration that allows for
closer interaction with the lifecycle of systemd units by using DBus
APIs directly instead of using systemctl. It is disabled by default, but
can be enabled by specifying `{ system.switch = { enable = false; enableNg = true; }; }`.

nixos/stc: Improve mount unit handling
We should sometimes restart the units rather than reloading them so the
changes are actually applied. / and /nix are explicitly excluded because
there was some very old issue where these were unmounted. I don't think
this will affect many people since most people use fstab mounts instead
but I plan to adapt this behavior for fstab mounts as well in the future
(once I wrote a test for the fstab thingies).

8022c82a39 nixosTests.switchTest: fix race condition on /testpath
Currently the test-watch.service gets started in a loop as long as
/testpath exists, so `rm /testpath /testpath-modified` runs into a race
condition where if the service was just getting activated, it will
create /testpath-modified and make the test fail.

This is fixed by making the service RemainAfterExit so that it only
starts once, and stopping it manually after we remove /testpath.

nixos/switch-to-configuration: Fix backslashes in unit names
systemd needs this so special characters (like the ones in wireguard
units that appear because they are part of base64) can be escaped using
the \x syntax.

Root of the issue is that `glob()` handles the backslash internally
which is obviously not what we want here.

Also add a test case and fix some perlcritic issues in the subroutine.

nixos/switch-to-configuration: Clean up lower part of the script
- Fully get rid of `parseKeyValues` and use systemctl features for that
- Add some regex modifiers recommended by perlcritic
- Get rid of a postfix if
- Sort units when showing their status
- Clean the logic for showing what failed from `elif` to `next`
- Switch from `state` to `substate` for `auto-restart` because that's
  actually where the value is stored
- Show status of units with one single systemctl call and get rid of
  COLUMNS in favor of --full
- Add a test for failing units

nixos/switch-to-configuration: Rework activation script restarts
This removes `/run/nixos/activation-reload-list` (which we will need in
the future when reworking the reload logic) and makes
`/run/nixos/activation-restart-list` honor `restartIfChanged` and
`reloadIfChanged`. This way activation scripts don't have to bother with
choosing between reloading and restarting.

Revert "Merge pull request #141192 from helsinki-systems/feat/improved-socket-handling2"
This reverts commit 57961d2b83, reversing
changes made to b04f913afc.
(I.e. this reverts PR #141192.)

While well-intended, this change does unfortunately introduce very
serious regressions that are especially disruptive/noticeable on desktop
systems (e.g. users of Sway will loose their graphical session when
running "nixos-rebuild switch").

Therefore, this change has to be reverted ASAP instead of trying to fix
it in "production".
Note: An updated version should be extensively discussed, reviewed, and
tested before re-landing this change as an earlier version also had to
be reverted for the exact same issues [0].

Fix: #146727

nixos/switch-to-configuration: Improve socket support
This commit changes a lot more that you'd expect but it also adds a lot
of new testing code so nothing breaks in the future. The main change is
that sockets are now restarted when they change. The main reason for
the large amount of changes is the ability of activation scripts to
restart/reload units. This also works for socket-activated units now,
and honors reloadIfChanged and restartIfChanged. The two changes don't
really work without each other so they are done in the one large commit.

The test should show what works now and ensure it will continue to do so
in the future.

25bef2d8f9 treewide: simplify pkgs.stdenv.lib -> pkgs.lib
The library does not depend on stdenv, that `stdenv` exposes `lib` is
an artifact of the ancient origins of nixpkgs.

98419a0f64 nixos/tests/switch-test: Ensures the test fails on failure (#55744)
The `| tee` invocation always masked the return value of the
switch-to-configuration test.

```
~ $ false | tee && echo "oh no"
oh no
```

The added wrapper script will still output everything to stderr, while
passing failures to the test harness.

2f6148c743 nixos/system: make switch-to-configuration script pure.
Fixes #28443

Fixed few invocations to `systemctl` to have an absolute path. Additionally add
LOCALE_ARCHIVE so that perl stops spewing warning messages.
