Recent bhyve/ZFS related commits

For those that aren't constantly watching the source tree, there's been a few great commits recently.

bhyve now has full graphical console support, with access via vnc. This makes even more of a difference that I originally expected. Guests like Windows can now be installed without having to create custom installers. Just run one bhyve command and you can perform a full install via vnc. FreeBSD & most Linux distros can also be installed in the same way without having to run a separate bhyve loader or mess around with grub. The bhyve code is still not in HEAD but is fairly easy to build.

zfsd is now also in HEAD. This should finally allow FreeBSD to catch disk events when they happen, and actually make use of hot spares.

Thanks to all the people that made these things happen. :beer:
