This patch implements an outstanding TODO in ConnectivityService to add synchronization over the map of network request ids to network agent info objects. This structure is accessed from multiple threads: - Binder thread on public aidl methods, most notably via getDefaultNetwork(). - Internal handler. This leads to many race conditions that can crash the system server and reboot the phone if getDefaultNetwork() is called on a Binder thread to service a public ConnectivityManager api while the default network state is being updated on the internal handler after losing the default network.
