gst/playback/gstplaybasebin.c: Don't remove our mute-probe if someone else already did so.
Original commit message from CVS: * gst/playback/gstplaybasebin.c: (mute_stream), (setup_substreams): Don't remove our mute-probe if someone else already did so. Don't set a 2nd one if there is already one pending on the pad. * gst/playback/gstplaybin.c: (gst_play_bin_send_event_to_sink), (do_playbin_seek): When a seek fails, ensure that playbin is still set back to playing. * gst/typefind/gsttypefindfunctions.c: (mpeg_ts_probe_headers), (mpeg_ts_type_find), (plugin_init): Add a typefind function for mpeg-ts streams.
