To prevent forgetting the base snapshot of a running backup, and catch

This reverts commit d53fbe2474.
The HashSet and "register" function are unnecessary, as we already know
which backup is the one we need to check: the last one, stored as
'last_backup'.

An flock on the snapshot dir itself is used in addition to the group dir
lock. The lock is used to avoid races with forget and prune, while
having more granularity than the group lock (i.e. the group lock is
necessary to prevent more than one backup per group, but the snapshot
lock still allows backups unrelated to the currently running to be
forgotten/pruned).

Attempt to lock the backup directory to be deleted, if it works keep the
lock until the deletion is complete. This way we ensure that no other
locking operation (e.g. using a snapshot as base for another backup) can
happen concurrently.

If the datastore holds broken backups for some reason, do not attempt to
base following snapshots on those. This would lead to an error on
/previous, leaving the client no choice but to upload all chunks, even
though there might be potential for incremental savings.

When uploading an RSA encoded key alongside the backup,
the backup would fail with the error message: "wrong blob
file extension".
Adding the '.blob' extension to rsa-encrypted.key before the
the call to upload_blob_from_data(), rather than after, fixes
the issue.

Commit 9fa55e09 "finish_backup: test/verify manifest at server side"
moved the finished-marking above some checks, which means if those fail
the backup would still be marked as successful on the server.
Revert that part and comment the line for the future.

instead of bailing and stopping the entire GC process, warn about the

Used chunks are marked in phase1 of the garbage collection process by
using the atime property. Each used chunk gets touched so that the atime
gets updated (if older than 24h, see relatime).
Should there ever be a situation in which the phase1 in the GC run needs
a very long time to finish, it could happen that the grace period
calculated in phase2 is not long enough and thus the marking of the
chunks (atime) becomes invalid. This would result in the removal of
needed chunks.
Even though the likelyhood of this happening is very low, using the
timestamp from right before phase1 is started, to calculate the grace
period in phase2 should avoid this situation.

for encrypted chunks this is currently not possible, as we need the key

Signed-off-by: Fabian Grünbichler <f.gruenbichler@proxmox.com>
regular chunks are only decoded when their contents are accessed, in
which case we need to have the key anyway and want to verify the digest.
for blobs we need to verify beforehand, since their checksums are always
calculated based on their raw content, and stored in the manifest.
manifests are also stored as blobs, but don't have a digest in the
traditional sense (they might have a signature covering parts of their
contents, but that is verified already when loading the manifest).
this commit does not cover pull/sync code which copies blobs and chunks
as-is without decoding them.

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.
Note that most other errors will still cause it to bail out
(eg. errors creating files, or I/O errors while writing
the contents).
