The flag CA_FORMAT_SHA512_256 is used to switch between sha512 and sha256 to
calculate digest in casync.
As we use sha256, we can get rid of this flag for now.

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.

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.

In order to restore only directories when some of their content fully matched
a match pattern on partial restores, these directories and their metadata are
pushed onto this buffer and only restored successivley on demand.

This structure contains all the attributes allowing to easily store those within
a e.g. dir buffer.

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.
