Requires updating the AsyncRead implementation to cope with byte-wise
seeks to intra-chunk positions.
Uses chunk_from_offset to get locations within chunks, but tries to
avoid it for sequential read to not reduce performance from before.
AsyncSeek needs to use the temporary seek_to_pos to avoid changing the
position in case an invalid seek is given and it needs to error in
poll_complete.

We support using an ext4 mountpoint directly as datastore and even do
so ourself when creating one through the disk manage code.
Such ext4 ountpoints have a lost+found directory which only root can
traverse into. As the GC list images is done as backup:backup user
walkdir gets an error.
We cannot ignore just all permission errors, as they could lead to
missing some backup indexes and thus possibly sweeping more chunks
than desired. While *normally* that should not happen through our
stack, we had already user report that they do rsyncs to move a
datastore from old to new server and got the permission wrong.
So for now be still very strict, only allow a "lost+found" directory
as immediate child of the datastore base directory, nothing else.
If deemed safe, this can always be made less strict. Possibly by
filtering the known backup-types on the highest level first.

otherwise we leak those descriptors and run into EMFILE when a backup
group contains many snapshots.
fcntl::openat and Dir::openat are not the same ;)

also when they have been removed/forgotten since we retrieved the
snapshot list for the currently syncing backup group.

modelled after the PVE one, but we are not 1:1 compatible and need
deleteEmpty support. For now let's just have some duplicate code, but
we should try to move this to widget toolkit ASAP.

This aligns it with PVE and allows the widget toolkit's update window
"refresh" to work without modifications once POST /apt/update is
implemented.

While we do not yet support the date specs for CalendarEvent the left
out "weekly" special expression[0] dies not requires that support.
It is specified to be equivalent with `Mon *-*-* 00:00:00` [0] and
this can be implemented with the weekday and time support we already
have.

when a datastore has enough data to calculate the estimated full date,
but always has exactly the same usage, the factor b of the regression
is '0'
return 0 for that case so that the gui can show 'never' instead of
'not enough data'

Adding a note about the garbage collection's grace period due to the

not freed immediately.

certain filesystems cannot be used as chunkstores, because they don't
support 2^16 subdirectories (e.g. ext4 with certain features disabled
or ext3 - see ext4(5))

JSON keys MUST be quoted. this is a one-time break in signature
validation for backups created with the broken canonicalization code.
QEMU backups are not affected, as libproxmox-backup-qemu never linked
the broken versions.

Change the .pxarexclude parser to byte based parsing with
`.split(b'\n')` instead of `.lines()`, to not panic on
non-utf8 paths.
Specially deal with absolute paths by prefixing them with
the current directory.

As else this is really user unfriendly, and it not printing it has no
advantage. If one doesn't wants to leak resource existence they just
need to *always* check permissions before checking if the requested
resource exists, if that's not done one can leak information also
without getting the path returned (as the system will either print
"resource doesn't exists" or "no permissions" respectively)
