Add a fuzz tester to the libarchive test suite. This

takes known-good archives, changes random bytes, then feeds
them through libarchive trying to provoke a crash or hang.

This has exposed a couple of problems reading malformed
ISO9660 images.  As a result, I now have a rewritten
Rockridge extension parser, better handling of malformed
PVDs, and some additional checks around end-of-archive conditions.
