Similar to the other drivers, virNetworkDriverState now has a virObject-derived object called virNetworkDriverConfig which is used for config items. As a starting point, the directory paths used by the network driver are moved there (again, parallelling what is done for other drivers). Using items in virNetworkDriverConfig is (yes, again) similar to using items in the other drivers' config - anything in the config object is immutable (once initialized), so the state object only needs to be locked while getting a reference to the config object, and then the members of the config object can be safely used until the config object is unrefed.
