137a6ebcad apt: allow changelog retrieval from enterprise repo
If a package is or will be installed from the enterprise repo, retrieve
the changelog from there as well (securely via HTTPS and authenticated
with the subcription key).

Extends the get_string method to take additional headers, in this case
used for 'Authorization'. Hyper does not have built-in basic auth
support AFAICT but it's simple enough to just build the header manually.

Take the opportunity and also set the User-Agent sensibly for GET
requests, just like for POST.

9e45e03aef tools/daemon: fix reload with open connections
instead of await'ing the result of 'create_service' directly,
poll it together with the shutdown_future

if we reached that, fork_restart the new daemon, and await
the open future from 'create_service'

this way the old process still handles open connections until they finish,
while we already start a new process that handles new incoming connections

3cd529ea51 tools: file logger: avoid some possible unwraps in log method
writing to a file can explode quite easily.
time formatting to rfc3339 should be more robust, but it has a few
conditions where it could fail, so catch that too (and only really
do it if required).

The writes to stdout are left as is, it normally is redirected to
journal which is in memory, and thus breaks later than most stuff,
and at that point we probably do not care anymore anyway.

It could make sense to actually return a result here..

3aade17125 tools: log rotate: compressing rotated files
We renamed the last one always to a file without compression
extension, even if it was .zst previously. So always add the correct
ending to the new last one, if compress was true.

Further, we cannot detect if there'd be a compression required if we
rotated (renamed) it already to the file with .zst included.

So check on rotation itself if it would be a "no .zst" -> ",zst"
transition, and call compress there.

it really should be OK now *knocking wood*

8b4f4d9ee4 tools/logrotate: fix compression logic
we never actually compressed any files, since we only looked at
the extension:
* if it was 'zst' (which was always true for newly rotated files), we
  would not compress it
* even if it was not 'zst', we compressed it inplace, never adding '.zst'
  (possibly compressing them multiple times as zstd)

now we add new rotated files simply as '.X' and add a 'target' to the
compress fn, where we rename it to (but now we have to unlink the source
path)

9e870b5f39 log rotate: do NOT compress first rotation
The first rotation is normally the one still opened by one or more
processes for writing, so it must NOT be replaced, removed, ..., as
this then makes the remaining logging, until those processes are
noticed that they should reopen the logfile due to rotation, goes
into nirvana, which is far from ideal for a log.

Only rotating (renaming) is OK for this active file, as this does not
invalidates the file and keeps open FDs intact.

So start compressing with the second rotation, which should be clear
to use, as all writers must have been told to reopen the log during
the last rotation, reopen is a fast operation and normally triggered
at least day ago (at least if one did not dropped the state file
manually), so we are fine to archive that one for real.
If we plan to allow faster rotation the whole rotation+reopen should
be locked, so that we can guarantee that all writers switched over,
but this is unlikely to be needed.

Again, this is was logrotate sanely does by default since forever.

e6ca9c3235 log rotate: do NOT overwrite file with possible writers
this is not the job of logrotate, and the real 20+ years battle
tested log rotate binary does not do so either as it's actually
pretty dangerous.

If we "replace" the file we break any logger which already opened a
new one here, e.g., a dameon starting up, and thus that writer would
log to nirvana.

It's the job of a logger to create a file if not existing, it makes
no sense to do it here.

735ee5206a fuse_loop: handle unmap on crashed instance
If a fuse_loop instance dies suddenly (e.g. SIGKILL), the FUSE mount and
loop device assignment are left behind. We can determine this scenario
on specific unmap, when the PID file is either missing or contains a PID
of a non-running process, but the backing file and potentially loop
device are still there.

If that's the case, do an "emergency cleanup", by unassigning the
loopdev, calling 'fusermount -u' and then cleaning any leftover files
manually.

With this in place, pretty much any situation is now recoverable via
only the 'proxmox-backup-client' binary, by either calling 'unmap' with
or without parameters.

2deee0e01f fuse_loop: add automatic cleanup of run files and dangling instances
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.

2d7d6e61be mount/map: use names for map/unmap for easier use
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.

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.
