Read image sizes (.pxar.fidx/.img.didx) from manifest and partition
sizes from /sys/...
Requires a change to ArchiveEntry, as DirEntryAttribute::Directory
does not have a size associated with it (and that's probably good).

to make the following cryptic error:
proxmox-file-restore failed: Error: Invalid byte 46, offset 5.
more understandable:
proxmox-file-restore failed: Error: Failed base64-decoding path '/root.pxar.didx' - Invalid byte 46, offset 5.
when a user passes in a non-base64 path but sets `--base64`.

For the actual partitions and blockdevices in a backup, which the
user sees like folders in the file-restore ui
Encoded as "None", to avoid cluttering DirEntryAttribute, where it
wouldn't make any sense to have.

These can't be entered or restored anyway, and cause issues with catalog
files for example.
Also a clippy fix.

The data on the restore daemon is either encoded into a pxar archive, to
provide the most accurate data for local restore, or encoded directly
into a zip file (or written out unprocessed for files), depending on the
'pxar' argument to the 'extract' API call.

Allows listing files and directories on a block device snapshot.
Hierarchy displayed is:
/archive.img.fidx/bucket/component/<path>
e.g.
/drive-scsi0.img.fidx/part/2/etc/passwd
(corresponding to /etc/passwd on the second partition of drive-scsi0)

Includes methods to start, stop and list QEMU file-restore VMs, as well
as CLI commands do the latter two (start is implicit).
The implementation is abstracted behind the concept of a
"BlockRestoreDriver", so other methods can be implemented later (e.g.
mapping directly to loop devices on the host, using other hypervisors
then QEMU, etc...).
Starting VMs is currently unused but will be needed for further changes.
The design for the QEMU driver uses a locked 'map' file
(/run/proxmox-backup/$UID/restore-vm-map.json) containing a JSON
encoding of currently running VMs. VMs are addressed by a 'name', which
is a systemd-unit encoded combination of repository and snapshot string,
thus uniquely identifying it.
Note that currently you need to run proxmox-file-restore as root to use
this method of restoring.

For now it only supports 'list' and 'extract' commands for 'pxar.didx'
files. This should be the foundation for a general file-restore
interface that is shared with block-level snapshots.
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.
