18210d8958 file-restore: use 'norecovery' for xfs filesystem
This allows mounting XFS partitons with 'dirty' states, like from a
running VM. Otherwise XFS tries to write recovery information, which
fails on a read-only mount.

606828cc65 file-restore: strip .img.fidx suffix from drive serials
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.

6a59fa0e18 file-restore: add size to image files and components
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).

4d0dc29951 file-restore: Add 'v' (Virtual) ArchiveEntry type
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.

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.

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)

d32a8652bd file-restore-daemon: add disk module
Includes functionality for scanning and referring to partitions on
attached disks (i.e. snapshot images).

Fairly modular structure, so adding ZFS/LVM/etc... support in the future
should be easy.

The path is encoded as "/disk/bucket/component/path/to/file", e.g.
"/drive-scsi0/part/0/etc/passwd". See the comments for further
explanations on the design.

Add a watchdog that will automatically shut down the VM after 10
minutes, if no API call is received.

dd9cef56fc file-restore-daemon: add binary with virtio-vsock API server
Implements the base of a small daemon to run within a file-restore VM.

The binary spawns an API server on a virtio-vsock socket, listening for
connections from the host. This happens mostly manually via the standard
Unix socket API, since tokio/hyper do not have support for vsock built
in. Once we have the accept'ed file descriptor, we can create a
UnixStream and use our tower service implementation for that.

The binary is deliberately not installed in the usual $PATH location,
since it shouldn't be executed on the host by a user anyway.

For now, only the API calls 'status' and 'stop' are implemented, to
demonstrate and test proxmox::api functionality.

Authorization is provided via a custom ApiAuth only checking a header
value against a static /ticket file.

Since the REST server implementation uses the log!() macro, we can
redirect its output to stdout by registering env_logger as the logging
target. env_logger is already in our dependency tree via zstd/bindgen.
