Christian EbnerandDietmar Maurer 8413083fc5 src/pxar/fuse.rs: Improve comments, add rustfmt skip tag and reafctor 
Also, removes an unused println statement in the decoder callback function and
fixes a typo.
Further, use ABI compatible Option<&T> for FFI to avoid use of raw pointers.

Christian EbnerandDietmar Maurer bbd055bf45 src/pxar/decoder.rs: impl functionality needed for fuse implementation 
Implements functions attributes, open, read, read_link and get_dir
to be used by the fuse implementation which uses file offsets within the archive
as inodes to reference the archives items.

Christian EbnerandDietmar Maurer f92e8266ae src/pxar/format_definitions.rs: move header type in PxarHeader and hash in PxarGoodbyeItem to top of struct 
By this it is possible to read and check just the first u64 of the corresponding
structs in order to identify the items.
This is needed for the fuse implementation in order to get entries based on the
archive offset, used as inode.
Directories are referenced by the offset to the goodbye tail while other items
are referenced by the offset of the filename followed by the entry.

Christian EbnerandDietmar Maurer 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 EbnerandDietmar Maurer 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.
