sysctl: support reading configuration from stdin and command line arguments (#39219)
This makes systemd-sysctl support following syntax, like
systemd-sysusers and systemd-tmpfiles:
```sh
$ /usr/lib/systemd/systemd-sysctl --inline 'foo.bar=42'
$ /usr/lib/systemd/systemd-sysctl - <<EOF
foo.bar=42
EOF
```
```
$ build/systemd-mute-console -q
Code should not be reached at src/mute-console/mute-console.c:103, function parse_argv(). Aborting. 💥
Aborted (core dumped)

copilot: Tell the AI to be thorough
At least when doing a local review, asking it to be thorough results
in a lot more comments on coding style violation so let's add such an
instruction to the global instructions.

Add copilot instructions
This was generated using copilot itself with Claude Sonnet 4.5 as
the backing model.
The idea is to test this out on some PRs to see whether copilot can
provide useful PR reviews. The idea is that it'll be able to take care
of the low hanging fruit like coding style issues and such. Once we get
some feedback on how it performs, we can make more changes to this document
to get it to behave better (assuming we decide to keep using it at all).

shared/bootspec: don't warn for new `loader.conf` options and correctly parse new `uki` and `profile` boot entry options (#39165)
Commit e2a3d562189c413de3262ec47cdc1e1b0b13d78b added the `uki` option
to sd-boot, and 1e9c9773b994f2f703a5aa5ba80961e90be3a892 added
`profile`, but because these were not added in src/shared/bootspec,
bootctl still shows warnings like `Unknown line 'uki', ignoring.` when
parsing the config. This PR allows parsing and displaying them correctly
in `bootctl` output. It also stops it from printing a warning for any of
the new `loader.conf` options (`log-level`, `reboot-on-error`, etc.).
Note that `uki-url` is still not handled as I can't easily test it.
man: fix advice regarding thread safety of libsystemd
The prohibition to move libsystemd objects between threads was added in 64a7ef8bc06b5dcfcd9f99ea10a43bde75c4370f ('man: be more explicit about thread
safety of sd_journal'). At the time, this was valid, because we were using the
mempool for allocation and it apparently didn't handle access from different
threads. Sadlly, the commit links to a bugzilla entry referenced in the commit
is not publicly visible anymore, so the details are murky. But we stopped using
the mempool in a5d8835c78112206bbf0812dd4cb471f803bfe88 ('mempool: only enable
mempool use when linked to libsystemd-shared.so'), with subsequent followup in b01f31954f1c7c4601925173ae2638b572224e9a ('Turn mempool_enabled() into a weak
symbol'). The restriction added in the man page is not necessary since then.
The text in the man page was arguably incorrect in calling the code
"thread-agnostic". If the code does not support being touched from threads at
all and has global state to tied to the main thread, it is not "agnostic", but
just doesn't support threads.
(I'm looking into https://github.com/systemd/python-systemd/issues/143, and
with the current scheme, the python-systemd module and all python code using
libsystemd would be very hard to use. With the change to free-threaded python
in python3.13, i.e. the replacement of single Global Interpreter Lock by
locking on individual objects, this limitation would become even more
constraining.)

TEST-74-AUX-UTILS: use sshd_config.d
* From the TEST-74-AUX-UTILS.ssh.sh writing directly into
/etc/ssh/sshd_config can hide config from distro using /usr/etc.

cases.
Most of those were dropped in 7d247d3cb875e1778e6cc81dbf255b13092b29e0. I left
behind the few cases where the 'output' name was different from the target name.
But we actually don't need those either, so get rid of those. (And one case
where I missed the name argument.)
No functional change, except that e.g. 'ninja -C build update-man-rules-impl'
doesn't work, but I hope nobody was using that.
Stop specifying license for generated file, instead mark as generated
I exclude generated files from license check, and I noticed
that this file was marked with a license header, which doesn't
make much sense, it is not copyrightable.

shared/bootspec: parse 'uki' boot entry option
Commit e2a3d562189c413de3262ec47cdc1e1b0b13d78b (as part of #36314)
makes sd-boot recognize a 'uki' stanza in a boot loader entry and
uapi-group/specifications@3f2bd8236d7f9ce6dedf8bda9cadffd0d363cb08 adds
it to the BLS, but bootctl and other components parsing said config do
not know about it, leading to the error message
`Unknown line 'uki', ignoring.` when attempting to parse the same entry.
This commit makes it get parsed the same way that that 'efi' is.
This adds what #39101 and #39070 did for the regular firstboot wizard
but for the homectl firstboot part: i.e. port to the generic prompt
loop, show the "chrome" bars, and mute the console.
And then it also makes querying for aux groups and shells optional,
because quite frankly, i am not sure what to answer there.
vmspawn: try to set up swtpm state for 4K RSA keys support
The next version of swtpm will support RSA4096, but it needs to be called
with a new parameter in order to do so. Try with it first, and if
execution fails, fallback to running without it.
This is especially needed for OBS builds, as the signing key is RSA4096
and cannot be changed by users, so the generated UKIs have RSA4096 signatures
for the pcrsig sections, and swtpm refuses them without the new support.
Revert "Bump required minimum version of libfido2 to 1.5.0" and add missing def instead
It helps nobody to break compatibility for a missing definition
for printing an error.
Just add the missing definition if not present, as it is already
done for thousands of others from the kernel, glibc, etc.
time-util: fix issues in parse_timestamp() and optimize performance
Previously, an input string ends with short timezone spec e.g. WET,
was parsed by setting $TZ environment variable to the timezone.
But the timezone might be different from the original local timezone,
thus the result might not follow the timezone change in the original
local timezone.
This makes the check of the short timezone spec with tzname[] earlier,
then it is not necessary to load another timezone file for e.g. WET,
and provides expected time.
This also make it use SAVE_TIMEZONE macro and drop use of forking
process. This makes greatly improve performance when parsing string
that contains timezone different from the current local timezone.
Unfortunately, there is still one corner case that our test fails.
When tzdata is built with rearguard enabled, then at least
Africa/Windhoek timezone does not provide correct time, but time shifted
1 hour from the original.
