Re-submit patch provided by David back in February when bhyve driver was not
in the tree. I did some changes to the patch on the way:
- rebase to the current master
- add ACL checks
- use bhyveDomObjFromDomain() instead of custom virDomainObjListFindByUUID()
- fix problems reported by 'syntax-check'

ACK. However, wait before pushing this one until after the release. It's
new feature not a bug fix after all.

Thanks for the review! When the freeze is over, I'll push after rebasing
and giving it one more round of testing to be sure.
