[Libguestfs] Fedora 18 / Rawhide switch over to using libvirt as the back end

Just a note [possibly more of a warning] that I'm intending to switch the default backend in Fedora 18+ to libvirt this week. For more information about what this means, see: https://rwmj.wordpress.com/2012/07/23/new-in-libguestfs-use-libvirt-to-la... Barring any bugs, the change ought to be transparent. The reasons why we're making this change in Fedora are: - Because in RHEL 7 this will be the default and we want to test it. - Improved encapsulation and security through sVirt. - Allows us to implement advanced features, especially disk hotplugging and access to remote disks. Note there's no change upstream. libvirt still isn't required.
