Christian Ebner 7750b7f2b7 pxar: decoder: take ownership of underlying reader
By taking ownership it is easier to move the decoder into another struct,
e.g. into a session context in fuse.

Christian Ebner 4d142ea79e pxar: cleanup: refactor and rename exclude pattern
The original name PxarExcludePattern makes no sense anymore as the patterns are
also used to match filenames during restore of the archive.

Therefore, exclude_pattern.rs is moved to match_pattern.rs and PxarExcludePattern
rename to MatchPattern.
Further, since it makes more sense the MatchTypes are now declared as None,
Positive, Negative, PartialPositive or PartialNegative, as this makes more sense
and seems more readable.
Positive matches are those without '!' prefix, Negatives with '!' prefix.

This makes also the filename matching in the encoder/decoder more intuitive and
the logic was adapted accordingly.

Christian Ebner beffac999f src/pxar/sequentail_decoder.rs: fix issue when restoring with glob pattern.
Partial extraction of an archive with a glob pattern, e.g. '**/*.conf' lead to
the unexpected behaviour of restoring all partially matched directories (in this
example all of them).

This patch fixes this unexpected behaviour by only restoring those directories
were the directory or one of its sub-items fully matched the pattern and should
therefore be restored.

To achive this behavoiur, directory metadata is pushed onto a stack and restored
on demand.

Christian Ebner 6a87910949 pxar: implement allow_existing_dirs for pxar decoder
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.

Christian Ebner d32c2e4d27 src/pxar/sequential_decoder.rs: adapt code for partial restore by match pattern
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).
