Title: Updated formula: libvirt

Upstream libvirt has moved to a new release process, with both a
stable release series, and a leading edge release series (roughly
monthly releases).

The update to this formula makes the stable series the default.

It also adds a new --devel option, to build from the latest
leading edge release instead, if desired.
