HAL nodedev driver builds fine on FreeBSD and basic stuff like
nodedev-list or nodedev-dumpxml works, but that's the only things that I
test for nodedev.

Also, I don't actually know what are the usage scenarios for the nodedev
APIs, I assume the main function is to use it to manage devices
passthrough to guests. For that case I doubt that important things like
device detaching work on FreeBSD, but probably I'm wrong because I didn't
look closer at this. Also, I didn't test PCI passthrough on FreeBSD at
all. 

Anyway, once somebody gets to implement passthrough related things for
libvirt on FreeBSD, probably it'd be good to base these things on the
existing HAL driver.

On the other hand, I'm not aware if somebody's going to implement it
soon and it's not on the top of my todo list either, so it would not be
a huge lost if it gets removed (not hard to revive it when needed).
