test: use KILL instead of SIGKILL in TEST-52-HONORFIRSTSHUTDOWN
SIG-prefixed signals for `kill` are not POSIX compliant, so on Ubuntu CI
(which defaults to dash instead of bash) the TEST-52 contains following
error:

core: set private section name for automount units
Because this was left unset, the unit_write_setting() function was
refusing to write out the automount-specific TimeoutIdleSec= and
DirectoryMode= settings when creating transient automount units.
Set it to the proper value in line with other unit types.
homectl: rework how we log when doing a home directory update
When updating a home directory we might update the record first, then
resize the image and finally synchronize the passwords to the storage
layers. These are three individually authenticated operations. Since
each might require touching a FIDO2 or PKCS#11 key we should say what we
are doing. Hence do so.
Usually we are pretty quiet with what we do, and let's stick to that.
Hence show this information only if we actually do more than one thing.
If we only update (and do not resize/sync passwords) then let's be quiet
as usual, as the command line then sufficiently clarifies what we are
doing.
homectl: do generic error handling/retry also when creating a home directory
After all, when creating we might need interaction with the security
token too, and our initial attempt to create the user will fail, since
we do not allow interactive auth on the security token, so that we then
can print a log message and retry with interactive auth then enabled.
user-record: rename JSON field "pkcs11Pin" to "tokenPin"
We'd like to use it for FIDO2 tokens too, and the concept is entirely
generic, hence let's just reuse the field, but rename it. Read the old
name for compatibility, and treat the old name and the new name as
identical for most purposes.

network: Introduce SR-IOV
SR-IOV provides the ability to partition a single physical PCI
resource into virtual PCI functions which can then be injected in
to a VM. In the case of network VFs, SR-IOV improves north-south n
etwork performance (that is, traffic with endpoints outside the
host machine) by allowing traffic to bypass the host machine’s network stack.
All devices behind a SPI controller have the same udev ID_PATH property.
This is a problem for predicable network names for CAN controllers.
CAN controllers, in contrast to Ethernet controllers, don't have a MAC
Address, so there's no way to tell two CAN controllers on the same SPI
host controller apart:

core: store timestamps of unit load attempts
When the system is under heavy load, it can happen that the unit cache
is refreshed for an unrelated reason (in the test I simulate this by
attempting to start a non-existing unit). The new unit is found and
accounted for in the cache, but it's ignored since we are loading
something else.
When we actually look for it, by attempting to start it, the cache is
up to date so no refresh happens, and starting fails although we have
it loaded in the cache.
When the unit state is set to UNIT_NOT_FOUND, mark the timestamp in
u->fragment_loadtime. Then when attempting to load again we can check
both if the cache itself needs a refresh, OR if it was refreshed AFTER
the last failed attempt that resulted in the state being
UNIT_NOT_FOUND.
Update the test so that this issue reproduces more often.

test: bump the timeout for systemd-hwdb-update.service under ASan
Since the hwdb update from a79be2f80777eb80e0d8177f6bccd7615de7ec1a
the systemd-hwdb-update service started timing out under ASan when
compiled with gcc, as we started tripping over the 3 minutes timeout.
This affects only gcc runs, since the current gcc on Arch still suffers
from the detect_stack_use_after_return performance penalty[0]. Until
the fixed gcc is present in the respective repositories, let's bump
the timeout to 4 minutes, as we might not be able to upgrade right
away, due to systemd/systemd#16199.

core: add device mapper to allow-list with DevicePolicy=closed and RootImage
To set up a verity/cryptsetup RootImage the forked child needs to
ioctl /dev/mapper/control and create a new mapper.
If PrivateDevices=yes and/or DevicePolicy=closed are used, this is
blocked by the cgroup setting, so add an exception like it's done
for loop devices (and also add a dependency on the kernel modules
implementing them).
logind: also cache LoaderEntryOneShot EFI variable
With this we are now caching all EFI variables that we expose as
property in logind. Thus a client invoking GetAllProperties() should
only trgger a single read of each variable, but never repeated ones.
The data from this EFI variable is exposed as dbus property, and gdbus
clients are happy to issue GetAllProperties() as if it was free. Hence
make sure it's actually free and cache LoaderConfigTimeoutOneShot, since
it's easy.

udev: split attribute assignment for MMC cards
Some cards have names consisting only of whitespace characters which

portabled: create temp file for unit, not directory
open_tmpfile_linkable is used to create a temporary file in the same
directory as the target, but portabled uses the name of the parent
directory instead of the file it intends to create.
In other words, it creats a tmp for /etc/systemd/system.attached instead
of /etc/systemd/system.attached/foo.service.
It still works because it's later moved in the right place.
But as a side effect, it tries the create the file in the parent directory
which is /etc/systemd, and it case of read-only filesystems it fails.
