that I've been working on but put off committing until after the RELENG_7 branch, including: * New manpages: cpio.5 mtree.5 * New archive_entry_strmode() * New archive_entry_link_resolver() * New read support: mtree format * Internal API change: read format auction only runs once * Running the auction only once allowed simplifying a lot of bid logic. * Cpio robustness: search for next header after a sync error * Support device nodes on ISO9660 images * Eliminate a lot of unnecessary copies for uncompressed archives * Corrected handling of new GNU --sparse --posix formats * Correctly handle a zero-byte write to a compressed archive * Fixed memory leaks Many of these improvements were motivated by the upcoming bsdcpio front-end. There have also been extensive improvements to the libarchive_test test harness, which I'll commit separately.
