mount: Include After=local-fs-pre.target by default in initrd
Although it may be true that /sysroot and its children don't belong in
local-fs.target, that doesn't mean they shouldn't come after
local-fs-pre.target. For instance, systemd-hibernate-resume@.service needs to
come before /sysroot and its children, but currently that only happens
coincidentally because of the ordering between systemd-fsck@.service and
local-fs-pre.target. As a result, mount units can be mistakenly started
simultaneously with systemd-hibernate-resume@.service, which can cause
corruption and data loss in the worst of cases.

dissect: allow setting "lo_file_name" field of loopback block devices
When attaching a loopback file this allows us to set an explicit name
for it. This is useful since it allows a caller to pre-select a string
that is directly attached to the loopback file. Via udev rules we'l
later make the device accessible through this name.
Note that "lo_file_name" is supposed to carry a file name of the backing
file, but the kernel actually does not care or enforce any of that, it
just stores the filename and returns it later. This makes it so useful,
as userspace has total control of that field.
"lo_file_name" should not be confused with the sysattr
"loop/backing_file" which is actually maintained by the kernel itself,
and always shows the file to the backing inode without userspace having
direct control over the returned string. Because the sysattr is
generated by the kernel it is subject to file system namespacing and
everything, while "lo_file_name" is not, it's really just a string
passed through the kernel.

This adds support for retrieving info about the inode backing a loopback

loopback device maintains.
A later patch uses this information to create block device symlinks in
/dev/ that allow refering block devices by their backing inodes. This is
useful when separate tools set up a loopback device from those which
ultimately shall mount them, and there shall be a stable reference be
passed along. For example, we can add a new kernel option setuploop= or
so which allows setting up a block device via a generator, and still
have a way to safely reference later.
And yes, this doesn't directly have anything to do with the probing
libblkid does, but it's close enough, and we have the device open anyway

udev_rules_parse_file: issue diagnostics about line continuation at EOF
When udev rules file ends with a line continuation, the parser
used to silently ignore the line without any diagnostics at all.
It's time to break the vow of silence and let the parser issue some
error diagnostics.

udevadm: introduce new 'verify' command
We seem to have no tool to verify udev rule files. There is a simple
udev rules syntax checker in the tree, test/rule-syntax-check.py, but
it is too simple to detect less trivial issues not detected by udev,
e.g. redundant comparisons (#26593) or labels without references.
Such a tool would be beneficial not only for maintaining udev rules
distributed along with udev, but also and even more so for maintaining
third party udev rules that are more likely to have issues with syntax
and semantic correctness.
Implement a udev rules syntax and semantics checker in the form of
'udevadm verify [OPTIONS] FILE...' command that is based on
udev_rules_parse_file() interface and would apply further checks
on top of it in subsequent commits.

udev_rules_parse_file: mark logged issues
Traditionally, all issues found in udev rules by udev_rules_parse_file()
are logged and ignored, so there was no mechanism to propagate the
information about these issues back to the caller.
Introduce such a mechanism by adding a new member to UdevRuleFile.
This new member is a bitmask describing which log levels were used
in messages logged with regards to the rule file.
This mechanism is going to be used by udevadm verify in subsequent
commits.

man: add mention that libsystemd uses getenv()
See #26688: getenv() is not thread-safe, and could a possible source of
problems when a multi-threaded program calls setenv()/putenv()/unsetenv() in
parallel. It is not possible to avoid getenv() calls in general, since $PATH,
$LANG, $SHELL, $USER, $HOME, $TZ may need to be accessed at any time.
Add a warning to our docs so that people are aware of the issue.
Closes #26688. (Real fixes will need to be in glibc and gnome-shell or other
programs.)
The text is added to threads-aware.xml to be included in various places. By
including it in libsystemd-pkgconfig.xml, it is automatically added to all sd-*
pages. The text is also included explicitly in pages for a few other functions
which are call getenv().

localed: skip verification when libxkbcommon is not installed
When compliled without libxkbcommon, we do no verification and accept the
arguments as given. When compliled against with, if dlopen() works, we do the
verification. But if dlopen() fails, we would refuse the call and return
SD_BUS_ERROR_INVALID_ARGS.
5de344704df64d8f31448f1222432bc87ddcfbef added things
this way when converting to dlopen(), but it seems not very useful: it can be
expected that when the library is supported but missing at runtime, we degrade
softly, and that the behaviour is something inbetween the cases of hard disable
at compilation time and full support. But right now we behave more strictly then
if disabled at compilation. Change the code to just warn if dlopen fails, but
accept the arguments.
(There are various minimization scenarios where forcing the installation of
libxkbcommon is not useful. E.g. a small installation where we want to set the
keymap via logind, but the configuration is managed by a configuration
management system and is known to be valid. Verification via libxkbcommon is
just overhead in this case.)
800f65f827c9828d4c872d44b19ca8a008505690 moved the check earlier, so now even
a noop case of setting the values that were already in place can fail.
