shared/bus-unit-util: add helper for ImportCredentialEx= and fix naming confusion
We add D-Bus properties like "*Ex" because we cannot change the D-Bus property
type without breaking backward comapatibility. But those names are only for
D-Bus, not for config file stanzas or the command-line parser. There, we can
change the type, or in other words, there is no type, just a free-form string
whose interpretation we can extend or change. Commit 831f208783aeac443e6f2fc2efc3119535a032ef that added ProtectHostnameEx was
confused, because it added ImportCredentialEx in places where parsing of
ImportCredential should be have been extended.
On D-Bus, we send ImportCrednential in preference, and ImportCredentialEx only
when required. This way we send less bytes on the wire and support older
systems that don't understand the new property.
logind: Don't match non-leader processes for utmp TTY determination (#38027)
This ensures we don't erroneously assign pseudoterminals created by
terminal emulators that use utempter to register themselves in utmp when
run under a GUI session that doesn't have a TTY assigned.
With these two changes the vscode parser works nicely again. Once the
EDG frontend adds support for this feature I'll fix it to check for the
fixed version like for GCC.
The EDG frontend is used by intellisense, which is the default
engine in VSCode, so parsing is currently broken and tons of
spurious errors are shown. Skip this feature when this
compiler frontend is used.

test-xattr-util.c: migrate to new assertion macros (#38025)

logind: pick up tty info from utmp only for tty sessions
Let's tighten the rules for picking up TTY information from utmp: let's
do so only for TTY session, nothing else. Apparently people have issues
with graphical sessions with certain terminal emulators that install
entries in utmp for each emulator window.

The tests are written and consumed by developers. Errno descriptions are good
for users, but for developers the errno "name" is actually more useful, and
we need to always map the description back to the name to compare with the
code. Let's make things simpler for ourselves by printing the errno names
directly.
Example output:
src/test/test-tests.c:15: Assertion failed: Expected "-1" to succeed, but got error: -1/EPERM
src/test/test-tests.c:16: Assertion failed: Expected "-ENOANO" to succeed, but got error: -55/ENOANO
src/test/test-tests.c:20: Assertion failed: Expected "0" to be positive, but it is zero.
src/test/test-tests.c:62: Assertion failed: Expected "RET_NERRNO(mkdir("/i/will/fail/with/enoent", 666))" to fail with error -55/ENOANO, but got -2/ENOENT
src/test/test-tests.c:68: Assertion failed: Expected "0" to fail with errno 2/ENOENT, but it succeeded
src/test/test-tests.c:70: Assertion failed: Expected "mkdir("/i/will/fail/with/enoent", 666)" to fail with errno 55/ENOANO, but got 2/ENOENT

src/test/test-cgroup-util.c:237: Assertion failed: Expected "r" to succeed, but got error: No such device or address

partially relaxed in e92d699dde746355bba893b2375b7937a52d9e05.
cg_pidref_get_unit() and cg_pid_get_slice() enter a deep chain of calls,
so it's hard to guess where the failure occurred. But those two calls
expect the cgroup path to be "well formed". When we're running in CI,
we don't have full control over what is happening on the machine,
so let's suppress that error too.
The error message is not always meaningful. Also, sometimes we care about the
sign of the value, and we ignore the sign of the error in the printing machinery.
The messages for errno are changed to say "errno" instead of "error". The problem with
the previous formalation is that our errors are always negative and errnos are
positive, so when we print the numerical value, we cannot use the word for both.
Example output:
src/test/test-tests.c:15: Assertion failed: Expected "-1" to succeed, but got error: -1/Operation not permitted
src/test/test-tests.c:16: Assertion failed: Expected "-ENOANO" to succeed, but got error: -55/No anode

tests: cast to intmax_t instead of printing to a temp buffer
We can do this for int types, i.e. the variants where we expect a
success/error code. The macros which do generating comparison operations
also support floats so we shouldn't use intmax_t there.
The code is shorter and calling printf once is certainly more efficient.

man/systemd-sysext: list ephemeral/ephemeral-import in the list of options
ephemeral/ephemeral-import are described as possible '--mutable' options but
not present in the list. Note, "systemd-sysext --help" lists them correctly.
systemd-journald.service conflicts with soft-reboot.target,
so make sure anything surviving soft-reboot and trying
to log to journal doesn't fail the socket units.
The commit naively returned early from socket_enter_running(), which however
is quite problematic, as the socket will be woken up over and over again
without doing a thing, until we eventually hit Poll/TriggerLimit*=.
On top of that it requires hacks to hold the start job for initrd-switch-root.service
up. Overall I doubt that is the right approach.
Let's instead hook this into our job engine, and try to activate
the service again when some other units are stopped. If all installed
jobs have been run yet we're still seeing the conflict or the manually
selected timeout is reached, fail the socket as before.
The offending commit tries to block systemd-udevd.service
from being activated during switch-root, but it is a dirty hack
and causes problems with e.g. Ctrl-Alt-Delete handling which
actually need to start a conflicting target. Let's revert
this here, and the original issue will be resolved in a cleaner
fashion in later commits.

nspawn: Add --bind-user-shell= to control shells for --bind-user
Prior to this change, no user shell can be specified in the user
records passed into a container via --bind-user=. This new option
allows users to:
1. When false (the default), continue to specify no user shell for
each bound user record, resulting in the use of the container's
default shell for bound users.
2. When true, include each host user's shell in the corresponding
user record passed into a container (via --bind-user=).
3. When an absolute path, set that path as the user shell for each
user record passed into a container (via --bind-user=).
This does not change the existing behavior, but allows users to
opt-in to either copy the shells specified by the host user records
or override the shell explicitly by path.

tree-wide: include unistd.h where necessary
We use symbols provided by unistd.h without including it. E.g.
open(), close(), read(), write(), access(), symlink(), unlink(), rmdir(),
fsync(), syncfs(), lseek(), ftruncate(), fchown(), dup2(), pipe2(),
getuid(), getgid(), gettid(), getppid(), pipe2(), execv(), _exit(),
environ, STDIN_FILENO, STDOUT_FILENO, STDERR_FILENO, F_OK, and their
friends and variants, so on.
Currently, unistd.h is indirectly included mainly in the following two paths:
- through missing_syscall.h, which is planned to covert to .c file.
- through signal.h -> bits/sigstksz.h, which is new since glibc-2.34.
Note, signal.h is included by sd-eevent.h. So, many source files
indirectly include unistd.h if newer glibc is used.
Currently, our baseline on glibc is 2.31. We need to support glibc older
than 2.34, but unfortunately, we do not have any CI environments with
such old glibc. CIFuzz uses glibc-2.31, but it builds only fuzzers, and
many files are even not compiled.

conf-files: fix an empty root handling in conf_files_list_strv()
Before 50c81130b69d04288f50217bede709bac6ca2b1a, the function used
chase(), hence if root is an empty string, each config directory made
prefixed with the current working directory if it is relative. See
implementation of chase().
With 50c81130b69d04288f50217bede709bac6ca2b1a, conf_files_list_strv()
internally uses chaseat(), hence each config directory is not prefixed
anymore even if it is relative.
To restore the previous behavior, this makes
- if root is an empty string, prefix each config directories with the
current working directory if relative.
- if root is relative, make it absolute to make the prefixed results also
absolute, and debugging logs show absolute paths.
- use chaseat_prefix_root() to prefix the results, for safety.
