Direct notification of network interface changes.

Browse Source 
Connectivity broadcasts recently changed and are no longer sent for
certain types of network changes.  For example, when stacked network
interfaces change for a mobile network.  To ensure that we pick up
all these details, directly wire the two services together.

Also remove some unused code for split network types.
