Stefan Reiter 66501529a2 file-restore: increase lock timeout on QEMU map
This lock is held during VM startup, so that multiple calls will not
start VMs twice. But this means that the timeout needs to incorporate
the time it might take a VM to boot, so increase it quite a bit.

This could previously lead to "interrupted system call" errors when
accessing backups with many disks.

Stefan Reiter 7d39e47182 file-restore: try to kill VM when stale
Helps to clean up a VM that has crashed, is not responding to vsock API
calls, but still has a running QEMU instance.

We always check the process commandline to ensure we don't kill a random
process that took over the PID.

Stefan Reiter b13089cdf5 file-restore: add 'extract' command for VM file restore
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.

Stefan Reiter 801ec1dbf9 file-restore(-daemon): implement list API
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)

Stefan Reiter 58421ec112 file-restore: add basic VM/block device support
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.
