Get and store the datastore's backend on local chunk reader
instantiantion and fetch chunks based on the variant from either the
filesystem or the s3 object store.
By storing the backend variant, the s3 client is instantiated only
once and reused until the local chunk reader instance is dropped.

Reupload the manifest to the S3 object store backend on manifest
updates, if s3 is configured as backend.
This also triggers the initial manifest upload when finishing backup
snapshot in the backup api call handler.
Updates also the locally cached version for fast and efficient
listing of contents without the need to perform expensive (as in
monetary cost and IO latency) requests.

Adds helper methods to generate the s3 object keys given a relative
path and filename for datastore contents or digest in case of chunk
files.
Regular datastore contents are stored by grouping them with a content
prefix in the object key. In order to keep the object key length
small, given the max limit of 1024 bytes [0], `.cnt` is used as
content prefix. Chunks on the other hand are prefixed by `.chunks`,
same as on regular datastores.
The prefix allows for selective listing of either contents or chunks
by providing the prefix to the respective api calls.

`BackupDir::is_protected` is the general helper method to check the
protected state for a snapshot. This checks for the presence of the
protected marker file, which is performed by stating the file and
requires traversing the full path.
When generating the backup list for a backup group, the snapshot
directory contents are however scanned nevertheless. Take advantage
of this by extending the regex used to filter contents by scandir to
include also the protected marker filename and set the state based on
the presence/absence, thereby avoiding the additional stat syscall
altogether.

to avoid issues when removing a group or snapshot directory where two
threads hold a lock to the same directory, move locking to the tmpfs
backed '/run' directory. also adds double stat'ing to make it possible
to remove locks without certain race condition issues.
this new mechanism is only employed when we can be sure, that a reboot
has occured so that all processes are using the new locking mechanism.
otherwise, two separate process could assume they have exclusive
rights to a group or snapshot.
bumps the rust version to 1.81 so we can use `std::fs::exists` without
issue.

We want to check the error code of zstd not to be 'Destination buffer
to small' (dstSize_tooSmall), but currently there is no practical API
that is also public. So we introduce a helper that uses the internal
logic of zstd to determine the error.
Since this is not guaranteed to be a stable api, add a test for that
so we catch that error early on build. This should be fine, as long as
the zstd behavior only changes with e.g. major debian upgrades, which
is normally the only time where the zstd version is updated.

Saves the currently active read/write operation counts in a file. The
file is updated whenever a reference returned by lookup_datastore is
dropped and whenever a reference is returned by lookup_datastore. The
files are locked before every access, there is one file per datastore.

Also moved pbs-datastore/src/crypt_config.rs to pbs-tools/src/crypt_config.rs.
We do not want to depend on pbs-api-types there, so I use [u8;32] instead of
Fingerprint.
pbs-datastore now ended up depending on tokio after all, but
that's fine for now
for the fuse code I added pbs-fuse-loop (has the old
fuse_loop and its 'loopdev' module)
ultimately only binaries should depend on this to avoid the
library link
the only thins remaining to move out the client binary are
the api method return types, those will need to be moved to
pbs-api-types...
