This is the equivalent of RequiresMountsFor=, but adds Wants= instead
of Requires=. It will be useful for example for the autogenerated
systemd-cryptsetup units.

Previously, we'd forward org.freedesktop.DBus.Local.Disconnected like
any other message to the other side. But that's not OK, as messages in
the org.freedesktop.DBus.Local.* namespace are supposed to never touch
the wire, and are synthetic messages that the library uses to
communicate with the app, but never with other apps.
dbus-daemon never cared, but dbus-broker complains about this, hence
clean this up.
See: #28514
This code doesn't link when gcc+lld is used:
$ LDFLAGS=-fuse-ld=lld meson setup build-lld && ninja -C build-lld udevadm
...
ld.lld: error: src/shared/libsystemd-shared-255.a(libsystemd-shared-255.a.p/cryptsetup-util.c.o):
symbol crypt_token_external_path@@ has undefined version
collect2: error: ld returned 1 exit status
As a work-around, restrict it to developer mode.
Closes https://github.com/systemd/systemd/issues/30218.
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=]

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.

Otherwise we get a not very nice message when trying to display a
non-existent man page:

Since we parse it on the other side via parse_percent() which requires
that, otherwise we get an error:

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.
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.
This should make sure our log lines look nice even if the tty we are
connected to is in raw mode. Normally, it's the TTY's job to turn an NL
we output into a CRNL and interpret it accordingly. However, if the tty
is in "raw" mode it won't do that. Specifically, this is controlled by
the ONLCR flag on the TTY. A TTY might be in raw mode if our "ptyfwd"
logic is used for example, where a 2nd tty is bi-directionally connected
to the primary tty, and duplicate processing is not desired.
Hence, let's just write out the CR on our own. This will make sure that
whenever we output something subsequent output always continues on the
beginning of the next line again, regardless the mode the TTY is in. Of
course, if the TTY is *not* in raw mode, then the extra CR we now
generate is redundant, but it shouldn't hurt either, as it just moves
the cursor to the front of the line even though already is just there.
We only to that if we actually talk to a TTY though, since we don't want
the extra CRs if we are redirected to a pipe or file or so. We are not
on Windows after all.
Fixes: #30155
This fixes a regression caused by 5ed73478e1
and aa6123e85e.
With these commits, when Reboot dbus method or friends is called,
reset_scheduled_shutdown() is called before shutting down the system,
so the wall message was cleared.
As the wall message itself is unrelated to the scheduling of shutting
down systems, let's keep the message.
Fixes#30167.
If the requested unit is not in the current working directory, it is not
necessary to include the current working directory in SYSTEMD_UNIT_PATH.
Follow-up for 45519d13a4.
Fixes#30166.
