2a088b9975 datastore: drop bogus chunk size check, can cause trouble
other sizes can happen in legitimate and illegitimate ways:
 - illegitimate: encryped chunks and bad actor client
 - legitimate: same chunk but newer zstd version (or compression
   level) can compress it better (or worse) so the

Ideally we could take the actual smaller chunk so that improved zstd
tech gets leveraged, but we could only allow to do that for
un-encrypted ones.

0408f60b58 datastore: add new Lookup for operations tracking
We sometimes need to do some in-memory only stuff, e.g., to check if
GC is already running for a datastore, which is a try_lock on a mutex
that is in-memory.

Actually the whole thing would be nicer if we could guarantee to hold
the correct contract statically, e.g., like

133d718fe4 split the namespace out of BackupGroup/Dir api types
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.

4c7cc5b39e datastore: add helpers to destroy whole namespaces
The behavior on "any snapshot was protected" isn't yet ideal, as we
then do not cleanup any (sub) namespace, even if some of them where
cleaned from groups & snapshots completely. But that isn't easy to do
with our current depth-first pre-order iterator behavior, and it's
also not completely wrong either, the user can re-do the removal on
the sub-namespaces, so leave that for later.

Should get moved to a datastore::BackupNamespace type once/if we get
one

dd612daab0 chunk_store: insert_chunk: write chunk again if it is empty on disk
and issue a warning. We can do this, because we know an empty chunk
cannot be valid, and we (assumedly) have a valid chunk in memory.

Having empty chunks on disk is currently possible when PBS crashes,
but the rename of the chunk was flushed to disk, when the actual data
was not.

If it's not empty but there is a size mismatch, return an error.

1eef52c206 datastore: move blob loading into BackupDir impl and adapt call sites
data blobs can only appear in a BackupDir (snapshot) in the backup
hierachy, so makes more sense that it lives in there.

As it wasn't widely used anyway it's easy to move the single
non-package call site over to the new one directly and drop the
implementation from Datastore completely.
