gst/rtsp/gstrtspsrc.*: Fix sending RTCP to the right place.
Original commit message from CVS: * gst/rtsp/gstrtspsrc.c: (gst_rtspsrc_init), (gst_rtspsrc_finalize), (gst_rtspsrc_stream_configure_transport), (gst_rtspsrc_handle_request), (gst_rtspsrc_loop_interleaved), (gst_rtspsrc_send_keep_alive), (gst_rtspsrc_loop_udp), (gst_rtspsrc_loop_send_cmd), (gst_rtspsrc_try_send), (gst_rtspsrc_open), (gst_rtspsrc_handle_message): * gst/rtsp/gstrtspsrc.h: Fix sending RTCP to the right place. Fix bug in reffing the wrong UDP element. Use new pad names for the session manager. Implement handling server requests in interleaved and UDP modes. Handle session keep-alive in UDP modes. Remove GCond for handling UDP timeouts. * gst/rtsp/rtspconnection.c: (rtsp_connection_connect), (rtsp_connection_send), (rtsp_connection_read), (read_body), (rtsp_connection_receive), (rtsp_connection_close): * gst/rtsp/rtspconnection.h: Store connection IP address for later. Add timeout args to all operations that might block forever. Parse session timeout. Only close sockets when not already closed. * gst/rtsp/rtspdefs.c: * gst/rtsp/rtspdefs.h: Add timeout return value and error string. * gst/rtsp/rtspmessage.c: (rtsp_message_init_response): Add small comment.
