This allows switching the base user identification/authentication method
in the rest server. Will initially be used for single file restore VMs,
where authentication is based on a ticket file, not the PBS user
backend (PAM/local).
To avoid putting generic types into the RestServer type for this, we
merge the two calls "extract_auth_data" and "check_auth" into a single
one, which can use whatever type it wants internally.

For now it only supports 'list' and 'extract' commands for 'pxar.didx'
files. This should be the foundation for a general file-restore
interface that is shared with block-level snapshots.
This is packaged as a seperate .deb file, since for block level restore
it will need to depend on pve-qemu-kvm, which we want to seperate from
proxmox-backup-client.

I made some comparision with bombardier[0], the one listed here are
30s looped requests with two concurrent clients:
[ static download of ext-all.js ]:
lvl avg / stdev / max
none 1.98 MiB 100 % 5.17ms / 1.30ms / 32.38ms
fastest 813.14 KiB 42 % 20.53ms / 2.85ms / 58.71ms
default 626.35 KiB 30 % 39.70ms / 3.98ms / 85.47ms
[ deterministic (pre-defined data), but real API call ]:
lvl avg / stdev / max
none 129.09 KiB 100 % 2.70ms / 471.58us / 26.93ms
fastest 42.12 KiB 33 % 3.47ms / 606.46us / 32.42ms
default 34.82 KiB 27 % 4.28ms / 737.99us / 33.75ms
The reduction is quite better with default, but it's also slower, but
only when testing over unconstrained network. For real world
scenarios where compression actually matters, e.g., when using a
spotty train connection, we will be faster again with better
compression.
A GPRS limited connection (Firefox developer console) requires the
following load (until the DOMContentLoaded event triggered) times:
lvl t x faster
none 9m 18.6s x 1.0
fastest 3m 20.0s x 2.8
default 2m 30.0s x 3.7
So for worst case using sligthly more CPU time on the server has a
tremendous effect on the client load time.
Using a more realistical example and limiting for "Good 2G" gives:
none 1m 1.8s x 1.0
fastest 22.6s x 2.7
default 16.6s x 3.7
16s is somewhat OK, >1m just isn't...
So, use default level to ensure we get bearable load times on
clients, and if we want to improve transmission size AND speed then
we could always use a in-memory cache, only a few MiB would be
required for the compressable static files we server.

by using our DeflateEncoder
for this to work, we have to create wrapper reader that generates the crc32
checksum while reading.
also we need to put the target writer in an Option, so that we can take
it out of self and move it into the DeflateEncoder while writing
compressed
we can drop the internal buffer then, since that is managed by the
deflate encoder now

implements a deflate encoder that can compress anything that implements
AsyncRead + Unpin into a file with the helper 'compress'
if the inner type is a Stream, it implements Stream itself, this way
some streaming data can be streamed compressed

Previously we did not store GROUP_OBJ ACL entries for
directories, this means that these were lost which may
potentially elevate group permissions if they were masked
before via ACLs, so we also show a warning.

Don't override `group_obj` with `None` when handling
`ACL_TYPE_DEFAULT` entries for directories.
Reproducer: /var/log/journal ends up without a `MASK` type
entry making it invalid as it has `USER` and `GROUP`
entries.

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

Pass in an optional auth tag, which will be passed as an Authorization
header on every subsequent call.
