[libvirt] [libvirt-gconfig PATCHv2 26/32] Add GVirConfigInterfaceNetwork



Make GVirConfigInterface an abstract base class, and move the
actual code in subclasses. This will make handling of the various
types of network interfaces more understandable and more logical
with respect to the corresponding XML.

v2: use g_return_if_fail to test function args for sanity
