we try to load the correct media in a loop until we find the correct tape.
when encountering an error or wrong tape, we want to log that (and send
an email if one is set) that requests the correct tape.
while trying to avoid printing the same errors more than once in a row,
we had at least one case (starting with an empty tape in the drive)
which would not print/send any tape request.
reworking that code to use a custom 'TapeRequest' enum, which contains
the state + error message, and a helper that prints and sends an email
when the state changes
this reduces the change check/log to a single variable, instead of 4
(tried, last_media_uuid, last_error, failure_reason)

Add test code to the first locate_file command, compute locate_offset.
Subsequent locate_file commands use that offset.

we have a static list of filesystems and their capabilities regarding
file attributes and fs features (e.g. sockets/fifos/etc) which also
includes xattrs,acls and fcaps
if we did not know a filesystem by its magic number (for example cephfs),
we did not even attempt to read xattrs, etc.
this patch adds those flags by default to unknown filesystems, and
removes them when we encounter EOPNOTSUPP (to remove the number
of syscalls)
with this, we should be able to catch xattrs/acls/fcaps on all
(unknown) fs types that support them

These require mounting using the regular 'mount' syscall.
Auto-generates an appropriate mount path.
Note that subvols with mountpoint=none cannot be mounted this way, and
would require setting the mountpoint property, which is not possible as
the zpools have to be imported with readonly=on.

Uses the ZFS utils to detect, import and mount zpools. These are
available as a new Bucket type 'zpool'.
Requires some minor changes to the existing disk and partiton detection
code, so the ZFS-specific part can use the information gathered in the
previous pass to associate drive names with their 'drive-xxxN.img.fidx'
node.
For detecting size, the zpool has to be imported. This is only done with
pools containing 5 or less disks, as anything else might take too long
(and should be seldomly found within VMs).

Even through best efforts at keeping it small, including the ZFS tools
in the initramfs seems to have exhausted the small overhead we had left
- give it a bit more RAM to compensate.
Also disable the ZFS ARC, as it's no use in such a memory constrained
environment, and we cache on the QEMU/rust layer anyway.

The future needs to be removed from the pending map in any case, even if
it returned an error, else all upcoming calls to access this key will
always return the same error.

sort the chunks we want to backup to tape by inode, to gain some
speed on spinning disks. this is done per index, not globally.
costs a bit memory, but not too much, about 16 bytes per chunk which
would mean ~4MiB for a 1TiB index with 4MiB chunks.

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)

Setting this to 0 is not just useless, but breaks the logic horribly
enough to cause random segfaults - better forbid this, to avoid someone
else having to debug it again ;)

admin/datastore reads linearly only, so no need for cache (capacity of 1
basically means no cache except for the currently active chunk).
mount can do random access too, so cache last 8 chunks for possibly a
mild performance improvement.

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).

Supports concurrent 'access' calls to the same key via a

underneath is only modified once a valid value has been retrieved.

Explicitly test that data will stay available and can be retrieved
immediately via listen(), even if the future producing the data and
notifying the consumers was already run in the past.
Wasn't broken or anything, but helps with understanding IMO.
