Add a new module containing key-related functions and schemata from all
over, code moved is not changed as much as possible.
Requires adapting some 'use' statements across proxmox-backup-client and
putting the XDG helpers quite cozily into proxmox_client_tools/mod.rs

of misspelled 'reserved' struct member, which where not used and
cargo build did not complain about the change, soo ...

plaintext backups, or about loading master keys when they are not
actually used for the current operation.

other more special usage scenarios as well.

this is stricter than the check that happened on manifest load, as it
also fails if the manifest is signed but we don't have a key available.
add some additional output at the start of a backup to indicate whether
a previous manifest is available to base the backup on.

- key passphrase change
- key decryption if not already set
- key encryption with master key

since we systemd-encode parts of the upid string, and those can contain
characters that are invalid in urls (e.g. '\'), we have to percent encode
those
add a 'percent_encode_component' helper, so that we can maybe change
the AsciiSet for all uses at the same time

A 'map' call will only clean up what it needs, that is only leftover
files or dangling instances of it's own name.
For a full cleanup the user can call 'unmap' without any arguments.
The 'cleanup on error' behaviour of map_loop is removed. It is no longer
needed (since the next call will clean up anyway), and in fact fixes a
bug where trying to map an image twice would result in an error, but
also cleanup the .pid file of the running instance, causing 'unmap' to
fail afterwards.

So user doesn't need to remember which loop devices he has mapped to
what.
systemd unit encoding is used to transform a unique identifier for the
mapped image into a suitable name. The files created in /run/pbs-loopdev
will be named accordingly.
The encoding all happens outside fuse_loop.rs, so the fuse_loop module
does not need to care about encodings - it can always assume a name is a
valid filename.
'unmap' without parameter displays all current mappings. It's
autocompletion handler will list the names of all currently mapped
images for easy selection. Unmap by /dev/loopX or loopdev number is
maintained, as those can be distinguished from mapping names.

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.
