Original commit message from CVS: * gst/rtsp/gstrtspsrc.c: (gst_rtspsrc_send), (gst_rtspsrc_open), (gst_rtspsrc_close), (gst_rtspsrc_play), (gst_rtspsrc_pause), (gst_rtspsrc_change_state): * gst/rtsp/gstrtspsrc.h: * gst/rtsp/rtspdefs.c: (rtsp_method_as_text), (rtsp_find_method): * gst/rtsp/rtspdefs.h: * gst/rtsp/rtsptransport.c: (rtsp_transport_parse): Handle RTSP defaults better. Issue OPTIONS request to figure out what we are allowed to do. Make the methods a bitfield so we can easily collect supported options. Fix rtsp_find_method. Do proper RTSP connection shutdown.
