Output is otherwise so weird, since this is the last log line seen for a
while typically, and if it doesn#t put the cursor back in the first
column it looks like something is incomplete and hanging. Hence do what
we always do: finish log messages with a newline.
To cut off a string at some position we must set the "precision" not the
field width in format strings.
This led to some assert()s being hit where they really should not be.
With gcc-13,
```
CFLAGS="-O3 -fno-semantic-interposition" meson setup build
```
triggers the following error:
```
../src/core/cgroup.c: In function ‘cgroup_context_dump’:
../src/core/cgroup.c:633:44: error: ‘%s’ directive argument is null [-Werror=format-overflow=]
633 | "%sDeviceAllow: %s %s\n",

cc1: some warnings being treated as errors
```
Fixes#30223.

This drops logs of failed unit tests in TEST-02-UNITTESTS from the journal,
as the expected logs from test-varlink-idl makes the post script fail.
Saving logs in journal is simply noisy, and we will output anyway after
qemu or nspawn finished by check_result_{qemu,nspawn}_unittests().
Our timestamp conversion roundtrip test was failing. But I think that this
is not our bug:
$ TZ='Africa/Khartoum' date --date='@1509482094'
Tue Oct 31 23:34:54 EAT 2017
$ TZ='Africa/Khartoum' date --date='Tue Oct 31 23:34:54 EAT 2017' +%s
1509485694
$ TZ='Africa/Khartoum' date --date='@1509485694'
Tue Oct 31 23:34:54 CAT 2017
$ echo $[1509485694 - 1509482094]
3600
This is essentially the same as what happens in our test. After a round-trip, we
end up one hour ahead.

This commit adds a hwdb entry for the Sony DVMC-DA1. This media converter
works with video capture software such as dvgrab, but it doesn't support
the AV/C command set and doesn't match the general entry.
It's been there since the test was introduced and I'm not really sure
what was the original intention behind it, but it makes systemd sad:
[ 4.909056] systemd[1]: /usr/lib/systemd/tests/testdata/units/testsuite-44.service:13: Unknown key name 'LogTarget' in section 'Service', ignoring.
Otherwise we get a not very nice message when trying to display a
non-existent man page:
~# systemctl cat test.service
[Unit]
Description=Hello
[Service]
ExecStart=true
~# systemctl help test.service
Documentation for (null) not known.
Since we parse it on the other side via parse_percent() which requires
that, otherwise we get an error:

The unit will be started or restarted a few times during boot, but but it has
StartLimitBurst = DefaultStartLimitBurst = 5, which means that the fifth
restart will already fail. On my laptop, I have exactly 4 restarts, so I don't
hit the limit, but on a slightly different system we will easily hit the limit.
In https://bugzilla.redhat.com/show_bug.cgi?id=2251394, there are five reloads
and we hit the limit.
Since 6ef512c0bb we propagate the start counter
over switch-root and daemon reloads, so it's easier to hit the limit during
boot.
In principle there might be systems with lots of vtcon devices, so let's just
allow the unit to be restarted without a limit.
Fixes https://bugzilla.redhat.com/show_bug.cgi?id=2251394.
This reverts commit 30462563b1.
fchmodat2(), while accepting AT_SYMLINK_NOFOLLOW as a valid flag,
always returns EOPNOTSUPP when operating on a symlink. The Linux kernel
simply doesn't support changing the mode of a symlink.
Fixes#30157
when KERNEL_INSTALL_UKIFY is not supplied we set ukify to $PWD/ukify
that will fail (perhaps only for manual installations):
FileNotFoundError: [Errno 2] No such file or directory: '/usr/src/linux-6.7-rc1/ukify'
this will make sure we have a sane default for UKIFY

The command arguments may contain spurious characters, e.g. line-break.
When we use command arguments as a description of a unit, we should
escape them.
Fixes#30187.
Turns out that redirecting a lot of output to the console can have some
funny effects, like random kernel soft lockups. I spotted this in
various CIs, but it remained almost entirely hidden thanks to
`softlockup_panic=1`, until 1a36d2672f which introduced a couple of
tests that log quite a lot in a short amount of time. This, in
combination with newer kernel version, which, for some reason, seem to
be more susceptible to such soft lockups, made the Arch Linux jobs soft
lockup quite a lot, see [0].
While debugging this I also noticed that runs which don't redirect
stdout/stderr to the console are noticeably faster, e.g.:
# TEST-71 nspawn + QEMU (KVM), StandardOutput=journal+console
Elapsed (wall clock) time (h:mm:ss or m:ss): 0:24.64
# TEST-71 nspawn + QEMU (KVM), StandardOutput=journal
Elapsed (wall clock) time (h:mm:ss or m:ss): 0:17.95
# TEST-71 nspawn + QEMU, StandardOutput=journal+console
Elapsed (wall clock) time (h:mm:ss or m:ss): 2:04.70
# TEST-71 nspawn + QEMU, StandardOutput=journal
Elapsed (wall clock) time (h:mm:ss or m:ss): 1:44.48
# TEST-04 QEMU, StandardOutput=journal+console
Elapsed (wall clock) time (h:mm:ss or m:ss): 4:22.70
# TEST-04 QEMU, StandardOutput=console
Elapsed (wall clock) time (h:mm:ss or m:ss): 5:04.67
Given all this, let's effectively revert ba7abf79a5, and dump the
testsuite-related journal messages only after the test finishes, so they
don't go through the slow console.

MemoryCurrent and MemoryAvailable are shown as "[not set]" when UINT64_MAX
(unset). Let's do the same for the newly-added Memory*{Current,Peak} properties.
