this makes it possible to only restore some snapshots from a tape media-set
instead of the whole. If the user selects only a small part, this will
probably be faster (and definitely uses less space on the target
datastores).
the user has to provide a list of snapshots to restore in the form of
'store:type/group/id'
e.g. 'mystore:ct/100/2021-01-01T00:00:00Z'
we achieve this by first restoring the index to a temp dir, retrieving
a list of chunks, and using the catalog, we generate a list of
media/files that we need to (partially) restore.
finally, we copy the snapshots to the correct dir in the datastore,
and clean up the temp dir

we have 2 modi in that window:
* backup has multiple datastores
* backup has single datastore
In the first case we show a 'mapping' grid so that
the user can only restore a part. Here a user sees all source
Datastores and can select a target for each one.
In the second case we only have a single 'Datastore' selector, but
we do not show the source. Because of this, the naming is slightly ambiguous
(is it the 'Source' or the 'Target' ?), so rename it to 'Target Datastore'.

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

in proxmox-backup-proxy, we log and discard any errors on 'accept',
so that we can continue to server requests
in proxmox-backup-api, we just have the StaticIncoming that accepts,
which will forward any errors from the underlying TcpListener
this patch also logs and discards the errors, like in the proxy.
Otherwise it could happen that if the api-daemon has more files open
than the proxy, it will shut itself down because of a
'too many open files' error if there are many open connections
(the service should also restart on exit i think, but this is
a separate issue)

if a datastore or root is not used directly on the pool dir
(e.g. the installer creates 2 sub datasets ROOT/pbs-1), info in

dataset, which has no iostats itself in /proc/spl/kstat/zfs/
but only the pool itself

For now it only supports 'list' and 'extract' commands for 'pxar.didx'

This is packaged as a seperate .deb file, since for block level restore
it will need to depend on pve-qemu-kvm, which we want to seperate from
proxmox-backup-client.

this patch adds a wrapper struct for any writer that implements

potentially blocks
