EthernetManager is moving to the connectivity mainline module and some of its hidden methods are being exposed as module-lib APIs. This CL updates the implementation. 1. Rename onAvailabilityChanged to onInterfaceStateChanged in IEthernetServiceListener.aidl, to match the name of the public callback method. 2. Add the interface state, role and IpConfiguration to the callback, so that clients can use this information without having to call synchronous methods. 3. Call the new callback whenever any of the above parameters changes, or when a callback is registered. Also make some package-private methods in EthernetNetworkFactory protected @VisibleForTesting because otherwise mockito can't mock them.
