the snapshot string format is not backwards compatible since it now has
an in-line namespace prefix. it's possible to select which magic to use
at the start of the backup, since a tape backup job knows whether it
operates on non-root namespaces up-front.
the MediaCatalog itself also has a similar incompatible change, but
there
- updating existing catalogs in-place
- not knowing what the catalog will contain in the future when initially
creating/opening it
makes bumping the magic there harder. since the tape contents are
sufficiently guarded by the other two bumps, ignoring the
backwards-incomaptible change of the on-disk catalogs seems like an okay
tradeoff.

by adding a new parameter 'namespaces', which contains a mapping
for a namespace like this:
store=datastore,source=foo,target=bar,max-depth=2
if source or target are omitted the root namespace is used for its value
this mapping can be given several times (on the cli) or as an array (via
api) to have mappings for multiple datastores
if a specific snapshot list is given simultaneously, the given snapshots
will be restored according to this mapping, or to the source namespace
if no mapping was found.
to do this, we reutilize the restore_list_worker, but change it so that
it does not hold a lock for the duration of the restore, but fails
if the snapshot does exist at the end. also the snapshot will now
be temporarily restored into the target datastore into the
'.tmp/<media-set-uuid>' folder.

both used the 'Display' trait of pbs_datastore::BackupDir, which is not
intended to be serialized anywhere. Instead, manually format the path
using the print_ns_and_snapshot helper, and conversely, parse with
'parse_ns_and_snapshot'. to be a bit safer, change the register_snapshot
signature to take a BackupNamespace and BackupDir instead of a string.

when continuing a media set, we first move to the end of the tape and

last line is 'moving to end of media' even if we already startet
writing. To make this less confusing, log that we arrived at the

There is a race upon reload, where it can happen that:
1. systemd forks off /bin/kill -HUP $MAINPID
2. Current instance forks off new one and notifies systemd with the
new MAINPID.
3. systemd sets new MAINPID.
4. systemd receives SIGCHLD for the kill process (which is the current
control process for the service) and reads the PID of the old
instance from the PID file, resetting MAINPID to the PID of the old
instance.
5. Old instance exits.
6. systemd receives SIGCHLD for the old instance, reads the PID of the
old instance from the PID file once more. systemd sees that the
MAINPID matches the child PID and considers the service exited.
7. systemd receivese notification from the new PID and is confused.
The service won't get active, because the notification wasn't
handled.
To fix it, update the PID file before sending the MAINPID
notification, similar to what a comment in systemd's
src/core/service.c suggests:
> /* Forking services may occasionally move to a new PID.
> * As long as they update the PID file before exiting the old
> * PID, they're fine. */
but for our Type=notify "before sending the notification" rather than
"before exiting", because otherwise, the mix-up in 4. could still
happen (although it might not actually be problematic without the
mix-up in 6., it still seems better to avoid).

without that one gets a "failed to lookup datastore X" in the log for
every datastore that is in read-only or offline maintenance mode,

Avoid that by first opening the datastore through a Lookup operation,
and only re-open it as Write op once we know that GC needs to get
scheduled for it.

We decided to go this route because it'll most likely be
safer in the API as we need to explicitly add namespaces
support to the various API endpoints this way.
For example, 'pull' should have 2 namespaces: local and
remote, and the GroupFilter (which would otherwise contain
exactly *one* namespace parameter) needs to be applied for
both sides (to decide what to pull from the remote, and what
to *remove* locally as cleanup).
The *datastore* types still contain the namespace and have a
`.backup_ns()` getter.
Note that the datastore's `Display` implementations are no
longer safe to use as a deserializable string.
Additionally, some datastore based methods now have been
exposed via the BackupGroup/BackupDir types to avoid a
"round trip" in code.
