Add the command `proxmox-backup-client group forget <group>` so
that we can forget (delete) whole groups with all the containing
snapshots.
To avoid printing full datastore paths (which are in the error messages)
we filter out the most common one (group not found) and rephrase it.

The lookahead cache size requires the resource limit for open file
handles to be high in order to allow for efficient reuse of unchanged
file payloads.
Increase the nofile soft limit to the hard limit and dynamically adapt
the cache size to the new soft limit minus the half of the previous
soft limit.
The `PxarCreateOptions` and the `Archiver` are therefore extended by
an additional field to store the maximum cache size, with fallback to
a default size of 512 entries.

Pxar archives allow to store additional information in a prelude
entry since pxar format version 2.
Add an optional parameter to `pxar` and `proxmox-backup-client` to
specify the path to restore the prelude to and pass this to the
archive extraction by extending the `PxarExtractOptions` by a
corresponding field. If none is given, the prelude is simply skipped
during restore.

Implement a method that prepares the decoder instance to access a
previous snapshots metadata index and payload index in order to
pass it to the pxar archiver. The archiver than can utilize these
to compare the metadata for files to the previous state and gather
reusable chunks.

To reuse dynamic entries of a previous backup run and index them for
the new snapshot. Adds a non-blocking channel between the pxar
archiver and the chunk stream, as well as the chunk stream and the
backup writer.
The archiver sends forced boundary positions and the dynamic
entries to inject into the chunk stream following this boundary.
The chunk stream consumes this channel inputs as receiver whenever a
new chunk is requested by the upload stream, forcing a non-regular
chunk boundary in the pxar stream at the requested positions.
The dynamic entries to inject and the boundary are then send via the
second asynchronous channel to the backup writer's upload stream,
indexing them by inserting the dynamic entries as known chunks into
the upload stream.

Whenever a split pxar archive is encountered, instantiate and attach

Piping the output to stdout is not possible for these, as this would

... and attach the split payload writer variant to the pxar archive
creation. By this, metadata and payload data will create different
dynamic indexes, allowing to lookup and reuse payload chunks without
the additional overhead of the pxar archive's metadata.
For now this functionality remains disabled and will be enabled in a
later patch once the logic for reusing the payload chunks is in
place.

... and adapt to the new reader/writer variant for encoder or
decoder/accessor to attach a dedicated payload input/output for split
pxar archives.
In preparation for look-ahead caching, where a passing around of
per-directory level encoder instances with internal references is
not feasible.
Previously, for each directory level a new encoder instance has been
generated, restricting possible implementation errors. These encoder
instances have been internally linked by references to keep track of
the state changes in a parent child relationship.
This is however not feasible when the encoder has to be passed by
mutable reference, as required by the look-ahead cache
implementation. The encoder has therefore been adapted to use a
single instance implementation with an internal stack keeping track
of the state.
Depends on the bumped pxar library version, including the patches to
attach the corresponding variant for the pxar reader/writer
instantiation.

Instead of composing the backup target name and pushing it to the
backup list, push the archive name and extension separately, only
constructing it while iterating the list later.
By this it remains possible to additionally prefix the extension, as
required with the separate pxar metadata and payload indexes.

Instead of taking ownership of the http client when starting a new
BackupWriter instance, only borrow the client.
This allows to reuse the http client to later reuse it to start also a
BackupReader instance as required for backup runs with metadata based
file change detection mode, where both must use the same http client.

Some filesystems (f.e. zfs) support xattrs bigger than 64kB, sadly we
can't get them because the kernel vfs limits us. The syscalls listxattr
and getxattr will return a E2BIG error in this case.
Added a flag --ignore-e2big-xattr to the client, this will ignore the
metadata (but still backup the file) if this error occurs.

Without this, only the outermost context is displayed, which in case
