* rework mount.c and swap.c to follow proper state enumeration/deserialization
semantics, like we do for device.c now
Features:
Deprecations and removals:
* Remove any support for booting without /usr pre-mounted in the initrd entirely.
Update INITRD_INTERFACE.md accordingly.
* 2019-10 – Remove POINTINGSTICK_CONST_ACCEL references from the hwdb, see #9573
* remove cgrouspv1 support EOY 2023. As per
https://lists.freedesktop.org/archives/systemd-devel/2022-July/048120.html
and then rework cgroupsv2 support around fds, i.e. keep one fd per active
unit around, and always operate on that, instead of cgroup fs paths.
* drop support for kernels that lack ambient capabilities support (i.e. make
4.3 new baseline). Then drop support for "!!" modifier for ExecStart= which
is only supported for such old kernels
* drop support for getrandom()-less kernels. (GRND_INSECURE means, once kernel
5.6 becomes our baseline). See

before that: at taint-flags/warn about kernels that lack
getrandom()/environments where it is blocked.
* drop support for LOOP_CONFIGURE-less loopback block devices (once baseline is
5.8)
* rework our PID tracking in services and so on, to be strictly based on pidfd,
once baseline is 5.13.
Features:
* add small wrapper around qemu that implements sd_notify/AF_VSOCK + machined and
maybe some other stuff and boots it
