[libvirt] [PATCH 1/6] conf: reimplement virDomainNetResolveActualType in terms of public API

Now that we have the ability to easily open connections to secondary
drivers, eg network:///system, it is possible to reimplement the
virDomainNetResolveActualType method in terms of the public API. This
avoids the need to have the network driver provide a callback for it.
