Add SignalingMessageReceiver class to listen to signaling messages
For now only WebRTC messages can be listened to, although it will be extended with other kinds later. This commit only introduces the base class, although it is not used yet anywhere; a concrete implementation will be added in a following commit. The test class is named "SignalingMessageReceiverWebRtcTest" rather than just "SignalingMessageReceiverTest" to have smaller, more manageable test classes for each listener kind rather than one large test class for all of them.
