Implements CLI-based single file and directory restore for both pxar.didx
archives (containers, hosts) and img.fidx (VMs, raw block devices). The design
for VM restore uses a small virtual machine that the host communicates with via
virtio-vsock.

This is encapsuled into a new package called "proxmox-file-restore", providing a
binary of the same name. A second package is provided in a new git repository
called "proxmox-backup-restore-image", providing a minimal kernel image and a
base initramfs (without the daemon, which is included in proxmox-file-restore).

The first couple patches in the proxmox-backup repo are adapted versions of the
ones Dominik sent to the list a while ago:
https://lists.proxmox.com/pipermail/pbs-devel/2020-December/001788.html

Dependency bump in proxmox-backup for pxar is required.

Tested with ext4 and NTFS VMs, but theoretically includes support for many more
filesystems.

Known issues/Missing features:
* GUI/PVE support
* PBS_PASSWORD/PBS_FINGERPRINT currently have to be set manually for VM restore
* ZFS/LVM/md/... support
* shell auto-complete for "proxmox-file-restore" doesn't seem to work (and I
  don't know why...)
* some patches might include some sneaky rustfmt/clippy fixes that'd better fit
  to a previous patch, sorry for that, rebasing so many patches is annoying ;)


v2:
* rebase on master
* drop applied patches
* pxar: make contents() call available without tokio-io feature (Wolfgang)
* pxar: drop peek() implementation, rework extractor to cope (Wolfgang)
* only move necessary functions to new key_source.rs (Dietmar)
* implement static ticket-based authentication for VMs, as relying on ports
  <1024 does not guarantee security (Dietmar, Wolfgang)
* allow running proxmox-file-restore as regular user by providing setuid-binary
  to start QEMU VMs (setgid kvm is not enough because of /dev/vhost-vsock)
  (Dietmar, Fabian)
* update debian/* with new proxmox-backup-restore-image naming (Thomas)
* encode zip file directly on the VM, only encode pxar when requested (Dominik)
* use tokio task in watchdog, instead of alarm() (Wolfgang)

...plus some reshuffling of patches because of all the changes from above, hope
I didn't miss anything big ;)
