Update to FreeBSD 9.2.

This required a lot of work to redo the ZFS install.sh. Under FreeBSD 9.2, you can no longer mount the temporary zroot under /mnt during the install, since / is a read-only filesystem (being the CD-ROM). I took the opportunity to remove a lot of the legacy cruft in install.sh, like all the gpart.nop hackery. Much was stolen from this procedure: https://wiki.freebsd.org/RootOnZFS/GPTZFSBoot
