Keep RTSPRequestEncoder, RTSPRequestDecoder, RTSPResponseEncoder and RTSPResponseDecoder for backwards compatibility but they now just extends the generic encoder/decoder and are markes as deprecated. Renamed the decoder test, because the decoder is now generic. Added testcase for when ANNOUNCE request is received from server. Created testcases for encoder. Mark abstract base classes RTSPObjectEncoder and RTSPObjectDecoder as deprecated, that functionality is now in RTSPEncoder and RTSPDecoder. Added annotation in RtspHeaders to suppress warnings about deprecation, no need when whole class is deprecated.
