Instead of deriving network identity based on raw subsystem broadcasts, listen for updates from ConnectivityService. Added atomic view of all active NetworkState, and build map from "iface" to NetworkIdentity set for stats tracking. To avoid exposing internal complexity, INetworkStatsService calls use general templates. Added TelephonyManager mapping to classify network types using broad labels like "3G" or "4G", used to drive templates. Cleaned up Objects and Preconditions.
