This adds the rules and starts those targets also for user instances.
Fixes #12330.

test: correctly fail when system is borked
In certain situations, the systemctl commands may fail (e.g. due to
missing shared libraries), but the 'script' continues and creates a
/testok file, marking the test incorrectly as passed. Let's fix this and
bail out immediately when a command exits with a non-zero exit code.

test: improve handling of ASan under clang
Running integration tests with ASan is somewhat tricky to begin with, as
we need to pre-load the ASan runtime DSO for certain services (like
dbus), otherwise they won't start or behave as expected. In case of gcc
this is pretty easy, as we need the runtime DSO during compilation, so
it's already present on the host system. For clang things get more
complicated, as ASan is compiled in statically by default, thus to
enable the necessary dynamic-ish behavior one needs to compile with
-shared-libasan and then correctly set LD_PRELOAD_PATH, as the runtime
libraries are not in a standard library path.

hwdb: Add support for Linx 12V64 (#12665)
This fixes the accelerometer for the Linx 12V64.
Note that even though the configuration for both models is the same, the 12V64 and 12X64 are different models.
test-execute: turn off coredump generation in test services
These services are likely to coredump, and we expect that but aren't
interested in the coredump. Hence let's turn off processing by setting
RLIMIT_CORE to 0/0.
test-execute: let's ignore the difference between CLD_KILLED and CLD_DUMPED
Depending on system configuration and whether SCMP_ACT_KILL_PROCESS or
SCMP_ACT_KILL_THREAD is available/used processes might coredump on
specific coredumps or are just plain killed. For our test case the
difference doesn't really matter, hence let's hide it away.
man: reword systemd.socket(5) description to avoid "file" when talking about services
This text was written a long time ago, when we mostly talked about "service
files". Strictly speaking, we don't need a "file", because the service might
be just an instance of a template, or an alias to another service. So let's use
the more modern parlance of "service units".

f5f07dbf06f6df9d12e092c05ad8cfbe244d203f adds VnetHeader= for tap

Add 8bit-version of get_process_cmdline() and use in cgroup-show.c
This restores show_pid_array() output in legacy locales on the console.
Only one call to get_process_cmdline() is changed, all others retain
utf8-only mode. This affects systemd-cgls, systemctl status, etc, when
working locally.
Calls to get_process_cmdline() that cross a process boundary always use
utf8. It's the callers responsibility to convert this to some encoding that
they use. This means that we always pass utf8 over the bus.
It turns out that the kernel allows comm names higher than our expected limit
of 16.
$ wc -c /proc/*/comm|sort -g|tail -n3
35 /proc/1292317/comm
35 /proc/1293610/comm
36 /proc/1287112/comm
$ cat /proc/1287112/comm
kworker/u9:3-kcryptd/253:0
The functions to retrieve and print process cmdlines were based on the
assumption that they contain printable ASCII, and everything else
should be filtered out. That assumption doesn't hold in today's world,
where people are free to use unicode everywhere.
This replaces the custom cmdline reading code with a more generic approach
using utf8_escape_non_printable_full().
For kernel threads, truncation is done on the parenthesized name, so we'll
get "[worker]", "[worker…]", …, "[w…]", "[…", "…" as we reduce the number of
available columns.
This implementation is most likely slower for very long cmdlines, but I don't
think this is very important. The common case is to have short commandlines,
and should print those properly. Absurdly long cmdlines are the exception,
which needs to be handled correctly and safely, but speed is not too important.
Fixes #12532.
v2:
- use size_t for the number of columns. This change propagates into various
other functions that call get_process_cmdline(), increasing the size of the
patch, but the changes are rather trivial.
