extract_sub_dir_seq, together with seq_files_extractor, allow extracting
files from a pxar Decoder, along with the existing option for an
Accessor. To facilitate code re-use, some helper functions are extracted
in the process.

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.

Don't override `group_obj` with `None` when handling
`ACL_TYPE_DEFAULT` entries for directories.
Reproducer: /var/log/journal ends up without a `MASK` type
entry making it invalid as it has `USER` and `GROUP`
entries.

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)

...to take advantage of the aio::Encoder from the pxar create.
Rather straightforward conversion, but does require getting rid of
references in the Archiver struct, and thus has to be given the Mutex
for the catalog directly. The callback is boxed.
archive_dir_contents can call itself recursively, and thus needs to
return a boxed future.
Users are adjusted, namely PxarBackupStream is converted to use an
Abortable future instead of a thread so it supports async in its handler
function, and the pxar bin create_archive is converted to an async API
function. One test case is made to just use 'block_on'.

There is no leading slash in an entry's full_path, causing an anchored
exclude at the root level to fail, e.g. having "/name" as the content of the
file archive/root/.pxarexclude didn't match the file archive/root/name
Fix this by prepending a leading slash before matching.

saves files mtime as i64 instead of u64 which enables backup of
files with negative mtime
the catalog_decode_i64 is compatible to encoded u64 values (if < 2^63)
but not reverse, so all "old" catalogs can be read with the new
decoder, but catalogs that contain negative mtimes will decode wrongly
on older clients
also remove the arbitrary maximum value of 2^63 - 1 for
encode_u64 (we just use up to 10 bytes now) and correctly
decode them and update the comments accordingly
adds also test for i64 encode/decode and for compatibility between
u64 encode and i64 decode

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).
