Based exclusively on work by Eric Blake in a patch posted with the same subject. However some modifications related to comments and my plans to add another backend.

Add a read-only udev based backend for virInterface. Useful for distros that do not have netcf support yet. Multiple libvirt based utilities use a HAL based fallback when virInterface is not available which is less than ideal.
