Allows mapping fixed-index .img files (usually from VM backups) to be
mapped to a local loopback device.
The architecture uses a FUSE-backed temp file mapped to a loopdev:
/dev/loopX -> FUSE /run/pbs-loopdev/xxx -> backup client -> PBS
Since unmapping requires some cleanup (unmap the loopdev, stop FUSE,
remove the temp files) a special 'unmap' command is added, which uses a
PID file to send SIGINT to the backup-client instance started with
'map', which will handle the cleanup itself.
The polling with select! in mount.rs needs to be split in two, since we
have a chicken and egg problem between running FUSE and setting up the
loop device - so we need to do them concurrently, until the loopdev is
assigned, at which point we can report success and daemonize, and then
continue polling the FUSE loop future.
A loopdev module is added to tools containing all required functions for
mapping a loop device to the FUSE file, with the ioctls moved into an
inline module to avoid exposing them directly.
The client code is placed in the 'mount' module, which, while
admittedly a loose fit, allows reuse of the daemonizing code.

we want to use dates for the calendarspec, and with that there are some
impossible combinations that cannot be detected during parsing
(e.g. some datetimes do not exist in some timezones, and the timezone
can change after setting the schedule)
so finding no timestamp is not an error anymore but a valid result

it really is not necessary, since the only time we are interested in
loading the state from the file is when we list it, and there
we use JobState::load directly to avoid the lock
we still need to create the file on syncjob creation though, so
that we have the correct time for the schedule
to do this we add a new create_state_file that overwrites it on creation
of a syncjob
for safety, we subtract 30 seconds from the in-memory state in case
the statefile is missing
since we call create_state_file from proxmox-backup-api,
we have to chown the lock file after creating to the backup user,
else the sync job scheduling cannot aquire the lock
also we remove the lock file on statefile removal

Errors while applying metadata will not be considered fatal
by default using `pxar extract` unless `--strict` was passed
in which case it'll bail out immediately.
It'll still return an error exit status if something had
failed along the way.

(eg. errors creating files, or I/O errors while writing
the contents).

To prevent a race with a background GC operation, do not allow deletion
of backups who's index might currently be referenced as the "known chunk
list" for successive backups. Otherwise the GC could delete chunks it
thinks are no longer referenced, while at the same time telling the
client that it doesn't need to upload said chunks because they already
exist.
Additionally, prevent deletion of whole backup groups, if there are
snapshots contained that appear to be currently in-progress. This is
currently unlikely to trigger, as that function is only used for sync
jobs, but it's a useful safeguard either way.
Deleting a single snapshot has a 'force' parameter, which is necessary
to allow deleting incomplete snapshots on an aborted backup. Pruning
also sets force=true to avoid the check, since it calculates which
snapshots to keep on its own.
To avoid code duplication, the is_finished method is factored out.

This can be "none", "encrypt" or "sign-only".

which previously did not take the above distinction into
account properly:
Both `BackupContent` and the manifest's `FileInfo`:
lose `encryption: Option<bool>`
gain `crypt_mode: Option<CryptMode>`

Behavior differs a bit. We write all non-loopback addresses to this
file, as the gui accepts connections from them all, so limiting it to
the first one is not really sensible.
Further an error to resolve, or only getting loopback addresses won't
write out an empty /etc/issue file, but a note about the error at the
place where the address would be displayed.
