By borrowing these objects we preserve the functionality but make sure
that ownership doesn't change, avoiding problems when contained within other
structs such as e.g. a buffer storing these attributes.

By default, restoring an archive will fail if files with the same filename
already exist in the target directory.
By setting the allow_existing_dirs flag, the restore will not fail if an
existing directory is encountered.
The metadata (permissions, acls, ...) of the existing directory will be set
to the ones from the archive.

To improve usability it is now possible to directly pass paths or match patterns
as arguments to pxar extract to partially restore an archive.
The patterns provided via CLI are appended to the ones read from file by the
--files-from option in order to have priority over those.

Allows to partially restore an archive by passing match patterns to the restore
function.
The whole restore is performed in sequential, therefore the whole archive has to
be read.
By wrapping the RawFd into an Option it can be controlled if the corresponding
part is restored (in case of Some(fd)) or if the Reader reads over it
without restore (in case of None).

By this the pxar integrity test checks for even more attributes such as a e.g.
correctly restored timestamp. See `man rsync` for details.

match_exclude_pattern() does not need a '&mut self' reference to the encoder,
move it therefore out of the impl.
Further, this patch contains some naming and formatting cosmetics.

dir_count was used to track the number of directory entries to store in the
archive and bail if the maximum is exceeded.
As the number of entries is equally obtained from the list of the filenames to
include, use that one instead.

Partial matches make only sense for directories, files are always leafs of the
tree. Take this into account in order to avoid restoring of files which only
matched the front of a match pattern.

In order to improve usablity, the target on archive extraction will be the
current working directory by default.
A different target can be provided via the optional --target <PATH> parameter.
