ext/dvdread/dvdreadsrc.c: Fix. Don't do one big huge loop around the whole DVD, that will cache all data and thus eat...

Don't do one big huge loop around the whole DVD, that will cache all data and thus eat sizeof(dvd) (several GB) before we see something. * gst-libs/gst/riff/riff-read.c: (gst_riff_read_seek): Actually NULL'ify event after using it. * gst/matroska/ebml-read.c: (gst_ebml_read_use_event), (gst_ebml_read_handle_event), (gst_ebml_read_element_id), (gst_ebml_read_element_length), (gst_ebml_read_element_data), (gst_ebml_read_seek), (gst_ebml_read_skip): Handle events. * gst/mpegstream/gstdvddemux.c: (gst_dvd_demux_base_init), (gst_dvd_demux_init), (gst_dvd_demux_get_audio_stream), (gst_dvd_demux_get_subpicture_stream), (gst_dvd_demux_plugin_init): Fix timing (this will probably break if I seek using menus, but I didn't get there yet). VOBs and normal DVDs should now work. Add a mpeg2-only pad with high rank so this get autoplugged for MPEG-2 movies. * gst/mpegstream/gstmpegdemux.c: (gst_mpeg_demux_base_init), (gst_mpeg_demux_class_init), (gst_mpeg_demux_init), (gst_mpeg_demux_new_output_pad), (gst_mpeg_demux_get_video_stream), (gst_mpeg_demux_get_audio_stream), (gst_mpeg_demux_get_private_stream), (gst_mpeg_demux_parse_packet), (gst_mpeg_demux_parse_pes), (gst_mpeg_demux_plugin_init): Use this as second rank for MPEG-1 and MPEG-2. Still use this for MPEG-1 but use dvddemux for MPEG-2. * gst/mpegstream/gstmpegparse.c: (gst_mpeg_parse_class_init), (gst_mpeg_parse_init), (gst_mpeg_parse_new_pad), (gst_mpeg_parse_parse_packhead): Timing. Only add pad template if it exists. Add sink template from class and not from ourselves. This means we will always use the correct sink template even if it is not the one defined in this file.
