Set PBS_QEMU_DEBUG=1 on a command that starts a VM and then connect to
the debug root shell via:
minicom -D \unix#/run/proxmox-backup/file-restore-serial-10.sock
or similar.
Note that this requires 'proxmox-backup-restore-image-debug' to work,
the postinst script is updated to also generate the corresponding image.

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.

Mostly in comments, but also email notification and two occurrences
of misspelled 'reserved' struct member, which where not used and
cargo build did not complain about the change, soo ...

we have information here not available in the access log, especially
if the /api2/extjs formatter is used, which encapsulates errors in a
200 response.
So keep the auth log for now, but extend it use from create ticket
calls to all authentication failures for API calls, this ensures one
can also fail2ban tokens.
Do that logging in a central place, which makes it simple but means
that we do not have the user ID information available to include in
the log.

daemon. Will be used to get the control socket of that one for access

reuse the FileLogger module in append mode.
As it implements write, which is not thread safe (mutable self) and
we use it in a async context we need to serialize access using a
mutex.
Try to use the same format we do in pveproxy, namely the one which is
also used in apache or nginx by default.
Use the response extensions to pass up the userid, if we extract it
from a ticket.
The privileged and unprivileged dameons log both to the same file, to
have a unified view, and avoiding the need to handle more log files.
We avoid extra intra-process locking by reusing the fact that a write
smaller than PIPE_BUF (4k on linux) is atomic for files opened with
the 'O_APPEND' flag. For now the logged request path is not yet
guaranteed to be smaller than that, this will be improved in a future
patch.

buildcfg.rs should contain convenience variables or macros
for using build-time configured variables
For now we replace hardcoded "/etc/proxmox-backup/<foo>"
with configdir!("<foo>").
