our export code can handle if the tape is inside the drive, so unloading
it first does not have an benefit, it even makes the exporting slower,
since we first unload it into its original slot, and then moving it
to an import/export slot
so drop the code that unloads the tape from the drive, and let the
export code itself handle that
change the 'eject' into a 'rewind' and comment why we do that first

'export_media' can handle if the tape is in either a normal slot of the
library, or in the drive assigned to the current pool writer.
(because we need to lock the drive)
if it is, for some reason, in a different drive, the error message
'media is not online'
could be slightly confusing for a user, since it would appear in the drive list
add the 'or a differen drive' to make it clearer

In order to avoid name conflicts with WorkerTaskContext
- renamed WorkerTask::log to WorkerTask::log_message
Note: Methods have different fuction signatures
Also renamed WorkerTask::warn to WorkerTask::log_warning for
consistency reasons.
Use the task_log!() and task_warn!() macros more often.
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.
locking during the tests as regular user failed because we try to
chown to the backup user (which is not always possible).
Instead, do not lock at all, by implementing 'open_backup_lockfile' with
'create_mocked_lock'

it seems that for some actions or in some circumstances, two minutes is
simply too short and the command aborts. Increase the default timeout to
10 minutes.
While it should give most commands enough time to finish, in case of a real
failure the procedure now takes up to 5 times longer, but IMHO thats an
OK tradeoff.

For some parts of the ui, we only need the snapshot list from the catalog,
and reading the whole catalog (can be multiple hundred MiB) is not
really necessary.
Instead, we write the list of snapshots into a seperate .index file. This file
is generated on demand and is much smaller and thus faster to read.
a test for a valid status_page, one with excess data
(in the descriptor as well in the page as a whole)
and a test with too little data

if the library sends more data than advertised, simply cut it off,
but if it sends less data, bail out (depending on how much data is
missing, trying to parse it could lead to a panic, so bail out early)

instead of having a public start/end_chunk_archive and register_chunks,
simply expose a 'register_chunk_archive' method since we always have
a list of chunks anywhere we want to add them

We get the descriptor length from the library and use that in
'chunks_exact', which panics on length 0. Catch that case
and bail out, since that makes no sense here anyway.
This could prevent a panic, in case a library sends wrong data.

instead of 'blindly' trusting the changer to deliver the fields written
in the specification, trust the length data it returns in the header.
we slice the descriptor data into equal sized chunks of the correct
size, then we do not have care bout the len and empty checks anymore
this also makes the code to read the rest of the page obsolete,
since the next descriptor is on the correct offset anyway

some libraries cannot handle a request with volume tags and DVCID set at
the same time.
So we make 2 separate requests and merge them, since we want to keep
the vendor/model/serial data.
to not overcomplicate the code, add another special type to ElementType

Some changers do not like the DVCID bit when querying non-drives,
this includes when querying 'all' elements.
To circumvent this, we query each type by itself (like mtx does it),
and only add the DVCID bit for drives (Data Transfer Elements).
Reported by a user in the forum:
https://forum.proxmox.com/threads/ibm-3584-ts3500-support.92291/
and limit to 1000 elements per request.
(Because some changers limit that request with the options we set)
instead of checking if the data len was equal to the allocation_len
for getting more data, we count the returned elements and compare
that with the number we requested

New kernel has stricter checks on tmpfs with stick-bit on directories, so some
commands (i.e. proxmox-tape changer status) fails when executed as root, because
permission checks fails when locking the drive.
This patch move the drive locks to /run/proxmox-backup/drive-lock.
Note: This is incompatible to old locking mechmanism, so users may not
run tape backups during update (or running backup can fail).
