In libarchive: Downgrade ARCHIVE_FATAL and ARCHIVE_FAILED errors which
occur on the write side of extracting a file to ARCHIVE_WARN errors
when returning them from archive_read_extract.
In bsdtar: Use the return code from archive_read_data_into_fd and
archive_read_extract to determine whether we should continue trying to
extract an archive after one of the entries fails.
This commit makes extracting a truncated tarball complain once about
the archive being truncated, instead of complaining twice (once when
trying to extract an entry, and once when trying to seek to the next
entry).
