machine: GC machine when no leader PID is set
After d8854ff1aca4434db0d7d6dcaf9fcf2f38105fb4, if a serialized
leader PID of a machine is already dead when deserialized, then the
leader PID and PIDFD are unset for the machine, and subsequent
machine_start() -> machine_watch_pidfd() will trigger an assertion.
This makes a Machine object without leader PID GCed.

mkosi: Enable EPEL for CentOS Stream tools tree
We need packages from EPEL to be able to build CentOS Stream images
with a CentOS Stream tools tree so enable it. This is broken on CentOS
Stream 10 but given using a CentOS Stream tools tree is broken without
EPEL as well, we might as well enable it and just wait until the packages
are added to EPEL 10.
Some of the field names between kernel and smbios spec differ. Kinda
confusing. Let's use the smbios field names, to match the CHID spec,
which also uses them, and thus be least confusing, treating kernel
attribute fields as an internal Linux thing only.
analyze: not all smbios fields are always defined, deal with that
As per previous commit, accept that not all SMBIOS fields are alwaysa
available (or set, but empty), hence handle this gracefully and don't
generate relevant CHIDs, as per docs.
chid-fundamental: not all SMBIOS fields are available on all systems
And the CHID documentation says that CHIDs that require fields that are
not available on the local system should not be generated. Follow that,
and generate a NULL CHID in that case (which we generally ignore
otherwise).
We nowadays support unprivileged invocation of systemd-nspawn +
systemd-vmspawn, but there was no support for discovering suitable disk
images (i.e. no per-user counterpart of /var/lib/machines). Add this
now, and hook it up everywhere.
Instead of hardcoding machined's, importd's, portabled's, sysupdated's
image discovery to RUNTIME_SCOPE_SYSTEM I introduced a field that make
the scope variable, even if this field is always initialized to
RUNTIME_SCOPE_SYSTEM for now. I think these four services should
eventually be updated to support a per-user concept too, this is
preparation for that, even though it doesn't outright add support for
this.
This is for the largest part not user visible, except for in nspawn,
vmspawn and the dissect tool. For the latter I added a pair of
--user/--system switches to select the discovery scope.
systemd-path: order all listed paths by their ID alphabetically
Let's add some system to the madness, given we added user-specific dirs
to the end of the list, but they should really be listed together with
the other user-specific ones.
sd-path: don't chop off trailing slash in sd_path apis, when user provided them
This is a minor compat break, but given the slow adoption of the
sd-path.h APIs I think it's one we should take. Basically, the idea is
that if the user provides a suffix path with a trailing slash (thus
encoding in the path that the last element must be a dir), we should
keep it in place, and not suppress it, in order to not willy nilly
reduce the amount of information contained in the path.
Simplifications that do not alter meaning, and do not suppress
information should be fine to apply to a path, but otherwise we really
should be conservative on this.

Add .venv to gitignore
This directory is commonly used for virtual Python environments.
These are useful when developing to install different Python versions
as well as install tooling like mkosi and mypy in an isolated fashion
without influencing the global system.

debug-generator: add a kernel cmdline option to pause the boot process (#35410)
Introduce the `systemd.break=` kernel command line option to allow
stopping the boot process at a certain point and spawn a debug shell.
After exiting this shell, the system will resume booting.
It accepts the following values:
- `pre-udev`: before starting to process kernel uevents (initrd and
host).
- `pre-basic`: before leaving early boot and regular services start
(initrd and host).
- `pre-mount`: before the root filesystem is mounted (initrd).
- `pre-switch-root`: before switching root (initrd).
[RFC] better naming for Azure MANA network devices (#34255)
The Azure MANA folks would like the PCI domain to be suppressed from
naming network interfaces. Let's introduce a somewhat generic way to do
this, without hardcoding anything to Azure.
Specifically: we'll ship a new hwdb entry that sets a new
ID_NET_NAME_INCLUDE_DOMAIN=0 property on relevant MANA devices. Then we
make net_id look for that property, and if it is set we simply suppress
the PCI domain.
(Untested as of now, needs feedback from Azure MANA folks that this
actually works and does what is requested here).

capability-util: generalize helper to acquire local caps (#35403)
This generalizes and modernizes the code to acquire set of local caps,
based on the code for this in the condition logic. Uses PidRef, and
acquires the full quintuplet of caps.
This can be considered preparation to one day maybe build without
libcap.

core/device: handle ID_PROCESSING udev property
If an enumerated device has ID_PROCESSING=1 property, and the service
manager does not know if the device has been processed by udevd
previously (that is, Device.deserialized_found does not have
DEVICE_FOUND_UDEV), then drop DEVICE_FOUND_UDEV flag from the device and
make the device not enter the active state.
