This commit adds the new varlink interface io.systemd.Machine at
/run/systemd/machine/io.systemd.Machine with a single method Register
It supports all combinations of RegisterMachine[WithSSH,WithNetwork] all
under the same method.
Use 'recommended' priority for the default compression library, to
indicate that it should be prioritized over the other ones, as it
will be used to compress journals/core files.
Also use 'recommended' for kmod, as systems will likely fail to boot
if it's missing from the initrd.
Use 'suggested' for everything else.
There is one dlopen'ed TPM library that has the name generated
at runtime (depending on the driver), so that cannot be added, as it
needs to be known at build time.
Also when we support multiple ABI versions list them all, as for the
same reason we cannot know which one will be used at build time.

This allows code to declare "weak" dlopen() style deps via an ELF
section following the just added specification.
The idea is that any user of dlopen() will place ELF_NOTE_DLOPEN(…)
somewhere close which will synthesize the note.
Tools such as rpm/dpkg package builders as well as initrd generators
(such as dracut) can then automatically pick up these weak deps of
suggested dependencies for their purposes.

If the file was removed by some other program, we should just go
to the next one without failing. item_do() is only used for recursive
globs instead of fixed paths so skipping on missing files makes sense
(unlike if the path was fixed where we should probably fail).
Fixes#32691 (hopefully)
Also adds three properties:
- VsockCid: the VSOCK CID of the VM
- SshAddress: the address of the VM in a format SSH can connect to
- SshPrivateKeyPath: the path to the SSH private key to use to connect
to the VM.
GetMachineSSHInfo is essentially a convenience method to query both the
SshAddress and SshPrivateKeyPath properties at once.
Currently test-aux-scope.service can get killed by the test before
it's had a chance to setup its signal handler. Make it Type=notify
to fix the race.
Fixes#32670 (hopefully)
Firstly, if we encounter an error when iterating over the directory, gather
the error but continue. This is unlikely to happen, but if it happens, then
it doesn't seem very useful to break the preset processing at a random
point. If we can't process a unit — too bad, but since we already might
have processed some units earlier, we might as well try to process the
remaining ones.
Secondly, add missing error codes for units that are in a bad state to the
exclusion list. Those, we report them in the changes list, but consider the
whole operation a success. (-ETXTBSY and -ENOLINK were missing.)
Thirdly, add a message generator for -ENOLINK.
Fixes https://github.com/systemd/systemd/issues/21224.
In the majority of cases, this is caused by
sleep_supported() returning error. Hence it's
very likely that it would fail again, so
the fallback is not really useful. Instead,
honor the --force option for these verbs.
