gst-libs/gst/interfaces/: Move interface for RTSP extensions from -good to here.
Original commit message from CVS: * gst-libs/gst/interfaces/Makefile.am: * gst-libs/gst/interfaces/rtspextension.c: (gst_rtsp_extension_get_type), (gst_rtsp_extension_iface_init), (gst_rtsp_extension_detect_server), (gst_rtsp_extension_before_send), (gst_rtsp_extension_after_send), (gst_rtsp_extension_parse_sdp), (gst_rtsp_extension_setup_media), (gst_rtsp_extension_configure_stream), (gst_rtsp_extension_get_transports), (gst_rtsp_extension_stream_select), (gst_rtsp_extension_send): * gst-libs/gst/interfaces/rtspextension.h: Move interface for RTSP extensions from -good to here. Added helper methods to invoke interface methods.
