openssl-util: allow to build with openssl without UI support
When OpenSSL is built without UI support, OPENSSL_NO_UI_CONSOLE is
defined. Or, even openssl is built with UI support, people may want to
build systemd without using OpenSSL's UI feature by specifying
-Dc_args='-DOPENSSL_NO_UI_CONSOLE=1'. This adds support for such cases.
Not tested, but hopefully, now systemd can be built with other ssl library,
like BoringSSL, which deos not support UIs.
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.

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

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

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.

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()

chase(), hence if root is an empty string, each config directory made

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.

resolved: when determining error to return, prefer "conclusive" over "inconclusive" errors
When asked to look something up, and all scopes we contact fail we need
to pick a suitable error code for the failure, and given that we look up
things on multiple scopes we might have multiple errors to choose from.
So far we simply picked the error from the last scope in the list, which
hence would be pretty arbitrary.
Let's tweak this a bit, and if we have multiple errors to choose from,
let's prefer "conclusive" failures over "inconclusive" ones. The
"inconclusive" ones in this sense are the ones where we didn't even issue
a request, but couldn't even do that because we had no server, no
network or things like that. The "conclusive" ones are the errors we got
from a server, that hence a "real" in a way.
This addresses the confusion described in #37969. For LLMNR lookups we
generally refuse looking up A addresses via IPv6 and AAAA via IPv4. This
generates a DNS_TRANSACTION_NO_SERVERS error, which we would then return
for one type of lookup but not for the other, because the IPv6 scope is
generally created after the IPv4 one, and hence so far won.
timer: Do not recalculate monotonic elapse time on clock change
The only clock change that affects monotonic timers is suspend causing
CLOCK_MONOTONIC to fall behind CLOCK_BOOTTIME. However, monotonic timers
that use CLOCK_BOOTTIME are not intended to have their elapse time
changed after a suspend. Hence condition the calculation of monotonic
timers’ elapse times on the cause not being a clock change.
