Stefan Reiter 45f9b32e0f client: implement map/unmap commands for .img backups
Allows mapping fixed-index .img files (usually from VM backups) to be
mapped to a local loopback device.

The architecture uses a FUSE-backed temp file mapped to a loopdev:

  /dev/loopX -> FUSE /run/pbs-loopdev/xxx -> backup client -> PBS

Since unmapping requires some cleanup (unmap the loopdev, stop FUSE,
remove the temp files) a special 'unmap' command is added, which uses a
PID file to send SIGINT to the backup-client instance started with
'map', which will handle the cleanup itself.

The polling with select! in mount.rs needs to be split in two, since we
have a chicken and egg problem between running FUSE and setting up the
loop device - so we need to do them concurrently, until the loopdev is
assigned, at which point we can report success and daemonize, and then
continue polling the FUSE loop future.

A loopdev module is added to tools containing all required functions for
mapping a loop device to the FUSE file, with the ioctls moved into an
inline module to avoid exposing them directly.

The client code is placed in the 'mount' module, which, while
admittedly a loose fit, allows reuse of the daemonizing code.

Dominik Csapak ba20987ae7 client/remote: add support to specify port number
this adds the ability to add port numbers in the backup repo spec
as well as remotes, so that user that are behind a
NAT/Firewall/Reverse proxy can still use it

also adds some explanation and examples to the docs to make it clearer
for h2 client i left the localhost:8007 part, since it is not
configurable where we bind to

Fabian Grünbichler 14f6c9cb8b chunk readers: ensure chunk/index CryptMode matches
an encrypted Index should never reference a plain-text chunk, and an
unencrypted Index should never reference an encrypted chunk.

Dietmar Maurer 2107a5aebc src/backup/manifest.rs: include signature inside the manifest
This is more flexible, because we can choose what fileds we want to sign.
