Drive serials have a character limit of 20, longer names like
"drive-virtio0.img.fidx" or "drive-efidisk0.img.fidx" would get cut off.
Fix this by removing the suffix, it is not necessary to uniquely
identify an image.

With the vsock-pkt-buffer fix in proxmox-backup-restore-image, we can
use way less memory for the VM without risking any crashes. 128 MiB
seems to be the lowest it will go and still be fully reliable.
While at it, add the "panic=1" argument to the kernel command line, so
in case the kernel *does* run out of memory, it will at least restart
automatically.

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.
