a771f90745 src/pxar/exclude_pattern.rs: do not return partial matches for files
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.

be9b39e17a src/pxar/sequential_decoder.rs: major refactoring of restore_sequential()
This splits the functionality of restore_sequential() into several smaller
functions in order to allow to reuse them when restoring by seeking based on
the goodbye table offsets.

48a4509c67 src/pxar/encoder.rs: fix bug with incorrect offset stored in goodbye table
Commit cd7dc87903 introduced the special treatment
for .pxarexclude files when stored in the archive.
The incorrect placement of a code snipplet from this path leads to an incorrect
offset and size stored in the goodbye table.
This fix places the start to the correct position, restoring the previously
correct behaviour.

cd7dc87903 pxar: impl .pxarexclude parsing and exclude matching
.pxarexclude files allow to exclude or include parts of a subtree by matching
with a glob pattern. The globs are used according to the matches of fnmatch.
In addition '**' can be used to match multiple directories within the path.

Order of the entries matter, as later ones win over previous ones.
As the .pxarexclude files can be placed at any node of the directory hirarchy,
this implies that matching child entries win over parent entries.
The only exception to this behaviour is, when a parent entry already fully
matched the path, thereby excluding the child entries which would match
otherwise.

e993db91cd pxar: introduce fs_feature_flags obtained from filesystem magic in Encoder
Not all filesystems support features such as xattrs,acl,... and trying to get
them is rather expensive.
By getting the supported features based on the filesystem magic and masking the
user set feature flags, unsupported features are excluded rather inexpensively
while encoding the archive.

a4cc8eb7c5 src/pxar/encoder.rs: check if ioctl supported by filesystem
Reading the quota project id relies on a ioctl call to get fsxattr.
On FUSE filesystems, ioctl calls might not be supported and will fail with
an errno indicating no support.
For these cases, the error is ignored and the default project id is used
(indicated by returning Ok(None)).
