tokios kill_on_drop sometimes leaves zombies around, especially
when there is not another tokio::process::Command spawned after
so instead of relying on the 'kill_on_drop' feature, we explicitly
kill the child on a worker abort. to be able to do this
we have to use 'tokio::select' instead of 'futures::select' since
the latter requires the future to be fused, which consumes the
child handle, leaving us no possibility to kill it after fusing.
(tokio::select does not need the futures to be fused, so we
can reuse the child future after the select again)

so that we can print a list at the end of the worker which backups
are corrupt.
this is useful if there are many snapshots and some in between had an
error. Before this patch, the task log simply says to 'look in the logs'
but if the log is very long it makes it hard to see what exactly failed.

The extraction algorithm has a state (bool) indicating
whether we're currently in a positive or negative match
which has always been initialized to true at the beginning,
but when the user provides a `--pattern` argument we need to
start out with a negative match.

This should never trigger if everything else works correctly, but it is
still a very cheap check to avoid wrongly marking a backup as "OK" when
in fact some chunks might be missing.

Multiple backups within one backup group don't really make sense, but
break all sorts of guarantees (e.g. a second backup started after a
first would use a "known-chunks" list from the previous unfinished one,
which would be empty - but using the list from the last finished one is
not a fix either, as that one could be deleted or pruned once the first
simultaneous backup is finished).
Fix it by only allowing one backup per backup group at one time. This is
done via a flock on the backup group directory, thus remaining intact
even after a reload.

To prevent a race with a background GC operation, do not allow deletion
of backups who's index might currently be referenced as the "known chunk
list" for successive backups. Otherwise the GC could delete chunks it
thinks are no longer referenced, while at the same time telling the
client that it doesn't need to upload said chunks because they already
exist.
Additionally, prevent deletion of whole backup groups, if there are
snapshots contained that appear to be currently in-progress. This is
currently unlikely to trigger, as that function is only used for sync
jobs, but it's a useful safeguard either way.
Deleting a single snapshot has a 'force' parameter, which is necessary
to allow deleting incomplete snapshots on an aborted backup. Pruning
also sets force=true to avoid the check, since it calculates which
snapshots to keep on its own.
To avoid code duplication, the is_finished method is factored out.

...when an entry is selected, that doesn't exist after the reload.
E.g. when one deletes selects a file within a snapshot and then clicks
the delete icon for said snapshot, focusRow would then fail and the
loading mask stay on until a reload.

The ' ' (space) between 'etc/ **/*.txt' resulted in the example command's output
not matching the given example output. Removing this space fixes the command.
This removes parts of the previous explanation of the tool that are no longer
correct, and adds an explanation of '--exclude' parameter, instead.
Adds more clarity to the command, by use of '/path/to/source' to signify
source directory.
Specify that the pattern matching style of the exclude parameter is that of
gitignore's syntax.

we do this by traversing the tree and marking elements as matches,

Even though it has nothing to do with vnc, we keep the name of the api
call for compatibility with our xtermjs client.
termproxy:
verifies that the user is allowed to open a console and starts
termproxy with the correct parameters
starts a TcpListener on "localhost:0" so that the kernel decides the
port (instead of trying to rerserving like in pve). Then it
leaves the fd open for termproxy and gives the number as port
and tells it via '--port-as-fd' that it should interpret this
as an open fd
the vncwebsocket api call checks the 'vncticket' (name for compatibility)
and connects the remote side (after an Upgrade) with a local TcpStream
connecting to the port given via WebSocket from the proxmox crate
to make sure that only the client can connect that called termproxy and
no one can connect to an arbitrary port on the host we have to include
the port in the ticket data
