Tim Kientzle 9dd49f960f Update libarchive to 2.4.10. This includes a number of improvements
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.
