Introduce archive_array_append to append a raw array to an archive_string
Introduce archive_array_append to append a raw array to an archive_string.
We need this for binary values in the PAX header.
We can append arbitray data to the archive_string since its string append
operations simply append at the end pointer rather than walking the string
and appending at the zero byte.
