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.
This also moves a couple of required utilities such as
logrotate and some file descriptor methods to pbs-tools.
Note that the logrotate usage and run-dir handling should be
improved to work as a regular user as this *should* (IMHO)
be a regular unprivileged command (including running
qemu given the kvm privileges...)

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...

move key_derivation to pbs-datastore
pbs-api-types should only contain "basic" types which
* are usually required by clients
* don't depend on pbs-related code directly

These are mostly tokio specific "hacks" or "workarounds" we
only really need/want in our binaries without pulling it in
via our library crates.

so that we can reuse that information
the removal of the adding to the corrupted list is ok, since
'get_chunks_in_order' returns them at the end of the list
and we do the same if the loading fails later in 'verify_index_chunks'
so we still mark them corrupt
(assuming that the load will fail if the stat does)

Implemented as a seperate struct SeekableCachedChunkReader that contains
the original as an Arc, since the read_at future captures the
CachedChunkReader, which would otherwise not work with the lifetimes
required by AsyncRead. This is also the reason we cannot use a shared
read buffer and have to allocate a new one for every read. It also means
that the struct items required for AsyncRead/Seek do not need to be
included in a regular CachedChunkReader.
This is intended as a replacement for AsyncIndexReader, so we have less
code duplication and can utilize the LRU cache there too (even though
actual request concurrency is not supported in these traits).

when we remove a datastore via api/cli, the proxy
has sometimes leftover references to that datastore in its
DATASTORE_MAP which includes an open filehandle on the
'.lock' file
this prevents unmounting/exporting the datastore even after removal,
only a reload/restart of the proxy did help
add a command to our command socket, which removes all non
configured datastores from the map, dropping the open filehandle

especially for the last group, without this the progress would report:
"percentage done: 100.00% (1 of 2 groups, 1 of 1 group snapshots)"

only check every 1024'th, which is cheaper to do than a modulo, as we
can just mask the 10 least-significant-bits and check if the result
is zero.

Fixes a non-negligible performance regression from commit
7f394c807b
While we skip known-verified chunks in the stat-and-inode-sort loop,
those are only the ones from previous indexes. If there's a repeated
chunk in one index they would get re-verified more often as required.
So, add the check again explicitly to the read+verify loop.

before reading the chunks from disk in the order of the index file,
stat them first and sort them by inode number.
this can have a very positive impact on read speed on spinning disks,
even with the additional stat'ing of the chunks.
memory footprint should be tolerable, for 1_000_000 chunks
we need about ~16MiB of memory (Vec of 64bit position + 64bit inode)
(assuming 4MiB Chunks, such an index would reference 4TiB of data)
two small benchmarks (single spinner, ext4) here showed an improvement from
~430 seconds to ~330 seconds for a 32GiB fixed index
and from
~160 seconds to ~120 seconds for a 10GiB dynamic index
