Re-enable network supportmarlin_12.92.0marlin/12.92.012.92.0

Rework network support code to use new connman-glib library instead
of the previously disabled agl-service-network API.  The only user
visible change is that a few extra previously exported header files
have been pruned from installation to avoid exposing GLib usage
and potentially requiring users needing to build against it.
