systemd[1016]: Failed to mount /tmp/app1 (type n/a) on /run/systemd/unit-extensions/1 (MS_BIND ): No such file or directory

Kernel commit dea2903719283c156b53741126228c4a1b40440f exposed (and
renamed) CIFS_MAGIC_NUMBER as CIFS_SUPER_MAGIC along with
SMB2_SUPER_MAGIC.
This fixes the following build fail on current Fedora Rawhide:
```
../src/basic/meson.build:389:8: ERROR: Problem encountered: found unknown filesystem(s) defined in kernel headers:
Filesystem found in kernel header but not in filesystems-gperf.gperf: CIFS_SUPER_MAGIC
Filesystem found in kernel header but not in filesystems-gperf.gperf: SMB2_SUPER_MAGIC
```

Commit a7fdc6c introduced a regression where file descriptors are opened
using O_PATH option. mac_smack_apply_fd() calls fsetxattr() and would fail
with a -EBADF (Bad file descriptor) error.
Use FORMAT_PROC_FD_PATH(fd) to convert the fd back into a full path and
call setxattr() or setfilecon() instead.

Rename the normalize_mounts() helper to drop_unused_mounts. All the
helpers called in there get rid of mounts that are unused for a variety
of reasons. And whereas the helpers are aptly prefixed with "drop" the
overall helper isn't and instead uses "normalize".
Make it more obvious what the helper actually does by renaming it from
normalize_mounts() to drop_unused_mounts(). Readers of code calling this
helper will immediately see that it will get rid of unused mounts.

If a service requests both ProtectSubset=pid and ProtectHostname=true
then it will currently fail to start. The ProcSubset=pid option
instructs systemd to mount procfs for the service with subset=pid which
hides all entries other than /proc/<pid>. Consequently trying to
interact with the two files /proc/sys/kernel/{hostname,domainname}
covered by ProtectHostname=true will fail.
Fix this by only performing this check when ProtectSubset=pid is not
requested. Essentially ProtectSubset=pid implies/provides
ProtectHostname=true.

With LTO, the compiler might think that the variable is uninitialized
(from NetworkManager's fork, with gcc-11.2.1-1.fc35):
src/libnm-systemd-core/src/libsystemd/sd-event/sd-event.c: In function 'sd_event_add_inotify':
src/libnm-systemd-core/src/libsystemd/sd-event/sd-event.c:2120: error: 's' may be used uninitialized in this function [-Werror=maybe-uninitialized]
2120 | *ret = s;
|
src/libnm-systemd-core/src/libsystemd/sd-event/sd-event.c:2102: note: 's' was declared here
2102 | sd_event_source *s;
|
lto1: all warnings being treated as errors
In particular, that would happen for codepaths where event_add_inotify_fd_internal()
returns `-errno`, and the compiler cannot be sure that the returned value will
be negative. Technically, the compiler is right, but we rely on libc functions
to set errno correctly, so this only happens in code paths, where something
bad already happend.
While LTO is prone to such false warnings, we are largely able to build systemd
without warnings. So it is feasible and we should make the effort of working
around warnings as they appear.

ELEMENTSOF(iovec) is not the correct value for the newly introduced parameter m
to function map_all_fields because it is the maximum number of elements in the
iovec array, including those reserved for N_IOVEC_META_FIELDS. The correct
value is the current number of already used elements in the array plus the
maximum number to use for fields decoded from the kernel audit message.

devices with the db_persist property won't be deleted during database
cleanup. This applies to dm and md devices in particular.
For such devices, we should also keep the files under /run/udev/links,
/run/udev/tags, and /run/udev/watch, to make sure that after restart,
udevd has the same information about the devices as it did before
the cleanup.
If we don't do this, a lower-priority device that is discovered in
the coldplug phase may take over symlinks from a device that persisted.
Not removing the watches also enables udevd to resume watching a device
after restart.

(cherry picked from commit 7ec624147a)
Currently if systemd-oomd doesn't kill anything in a selected cgroup, it
selects a new candidate immediately. But if a selected cgroup wasn't killed,
it is likely due to it disappearing or getting cleaned up between the time
it was selected as a candidate and getting sent SIGKILL(s). We should handle
it as though systemd-oomd did perform a kill so that it will check
swap/pressure again before it tries to select a new candidate.
(cherry picked from commit 914d4e99f4)
There can be a situation where systemd-oomd would kill all of the processes
in a cgroup, pid1 would clean up that cgroup, and systemd-oomd would get
ENODEV trying to iterate the cgroup a final time to ensure it was empty.
systemd-oomd sees this as an error and immediately picks a new candidate even
though pressure may have recovered. To counter this, check and handle
path unavailability errnos specially.

A rolling distro won't set VERSION_ID or SYSEXT_LEVEL in os-release,
which means we skip validation of ExtensionImages.
Validate even with just an ID, the lower level helper already
recognizes and accepts this use case.

The debug symbols are of very limited use in proper deployments
unlike with regular userspace. Unless someone goes through the pain
of setting up an EFI debugger (assuming their firmware even supports
this in the first place) any provided debug symbols will just be
useless.
Debugging under QEMU is possible, but even then it is non-trivial
to set up, so anyone willing to go that far can just build in
developer mode.
Meanwhile, at least x86 firmware tends to refuse binaries that contain
debug symbols. We do strip the files when converted to PE anyway, but
the elf file needs to stay around on other arches as objcopy does not
support PE as input there.
Also, the generated debug symbols seem to be not reproducible when
building with LTO. Whether this is an issue in tooling or our side
is unclear. This works around this issue.

The goal is to have the detection of features and paths done first, and
then the build target constructions second.

RouteTable=off was introduced to provide consistency with wg-quick
command. This makes the RouteTable= settings accepts other negative
boolean values.
(cherry picked from commit e135559d80)
Previously, we'd try to handle corruption by bumping the index even
if it was an entry array object that was corrupted (which we can't
deal with).
Now, we only try to deal with corrupted entry objects by moving the
corruption handling into generic_array_get().
On top, we also add an additional check for -EADDRNOTAVAIL which can
also be caused by corrupted journal data.

In particular, mention the contract the generator has with external
ExecCondition= binaries that may be provided by desktop environments.
But, also mention all the other relevant keys. In particular
X-systemd-skip= is important to be documented.
