c8f145adbb homed: don't insist on authentication against host-copy user record
homed maintains two or three copies of the user's identity record per
home directory: one on the host, one inside the LUKS header, and one
embedded in the home directory.

Previously we'd insist that if a user logs in they have to authenticate
against all three, as a safety feature. This broke logging into
unfixated records however, since in that case the host version is
synthetic and thus does not carry any authentication data.

Let's hence losen the strictness here: accept authentication against
host records that carry no auth data. This should be safe as we know
after all that the second/third record will catch invalid accesses.

c56463fdb4 meson: add fuzz-tests= option
The slow-tests= option already enables fuzzers as well, however, this
option can't be used in the "fully sanitized" runs, as certain slow
tests are affected by the performance quite significantly.

This option allows us to enable only fuzzers without the slow tests to
meet the needs of such runs.

efdbf5fe9c shared: treat generator units as vendor units
Units created with "systemctl edit --full" from generator units aren't
removed with "systemctl revert" because units in the generator,
generator_early, and generator_late paths aren't considered vendor
units.

Alter path_is_vendor() to return true if the given path is a
generator unit, which in turn causes "systemctl revert" to remove units
created with "systemctl edit --full" as they now have vendor versions.

9b3278d907 udev: rename the persistent link for ATA devices
ATA devices should use the ATA ids like port number and (possibly)
master/slave or multiplier id, not the generic SCSI ID.
Currently only port number is included in the link. With this patch
the link would be able to support more cases, which are a) when the
device is behind a port multiplexer b) the distinction between master
and slave (distinguished by target id).

I tried to verify scenario a) with this patch, but I failed to find a
machine with PMP SATA devices attached. But the link below
https://github.com/systemd/systemd/issues/3943
could show what's the difference. Here is my test for scenario b)

09835de3cc proc-cmdline: make checking of EFI options variable optional
And do not use it in the IMPORT{cmdline} udev code. Wherever we expose
direct interfaces to check the kernel cmdline, let's not consult our
systemd-specific EFI variable, but strictly use the actual kernel
variable, because that's what we claim we do. i.e. it's fine to use the
EFI variable for our own settings, but for the generic APIs to the
kernel cmdline we should not use it.

Specifically, this applies to IMPORT{cmdline} and
ConditionKernelCommandLine=. In the latter case we weren#t checking the
EFI variable anyway, hence let's do the same for the udev case, too.
