79e58a903e pxar: handle missing GROUP_OBJ ACL entries
Previously we did not store GROUP_OBJ ACL entries for
directories, this means that these were lost which may
potentially elevate group permissions if they were masked
before via ACLs, so we also show a warning.

cba167b874 pxar/extract: if possible create files sparesly
instead of filling them with zeroes

this fixes an issue where we could not restore a container with large
sparse files in the backup (e.g. a 10GiB sparse file in a container
with a 8GiB disk)

if the last operation of the copy was a seek, we need to truncate
the file to the correct size (seek beyond filesize does not change it)

d9b8e2c795 pxar: better error handling on extract
Errors while applying metadata will not be considered fatal
by default using `pxar extract` unless `--strict` was passed
in which case it'll bail out immediately.

It'll still return an error exit status if something had
failed along the way.

Note that most other errors will still cause it to bail out
(eg. errors creating files, or I/O errors while writing
the contents).

d44185c4a1 fix #2873: if --pattern is used, default to not extracting
The extraction algorithm has a state (bool) indicating
whether we're currently in a positive or negative match
which has always been initialized to true at the beginning,
but when the user provides a `--pattern` argument we need to
start out with a negative match.
