Increase max. buffer size because we cannot split buffers for ADPCM (screws references) and I've seen files with 2048 byte chunks. 4096 seems safe for now.

ext/dirac/: Do something. Don't actually know if this works because I don't have a demuxer yet. Original commit message from CVS: * ext/dirac/Makefile.am: * ext/dirac/gstdirac.cc: * ext/dirac/gstdiracdec.cc: * ext/dirac/gstdiracdec.h: Do something. Don't actually know if this works because I don't have a demuxer yet. * ext/gsm/gstgsmdec.c: (gst_gsmdec_getcaps): Add channels=1 to caps returned from _getcaps(). * ext/ogg/gstogmparse.c: (gst_ogm_audio_parse_get_type), (gst_ogm_video_parse_get_type), (gst_ogm_audio_parse_base_init), (gst_ogm_video_parse_base_init), (gst_ogm_parse_init), (gst_ogm_audio_parse_init), (gst_ogm_video_parse_init), (gst_ogm_parse_sink_convert), (gst_ogm_parse_chain), (gst_ogm_parse_change_state): Separate between audio/video so ogmaudioparse actually uses the audio pad templates. Both audio and video work now, including autoplugging. Also use sometimes-srcpad hack. * gst-libs/gst/riff/riff-read.c: (gst_riff_read_seek): Handle events better. Don't hang on infinite loops. * gst/avi/gstavidemux.c: (gst_avi_demux_class_init), (gst_avi_demux_init), (gst_avi_demux_reset), (gst_avi_demux_src_convert), (gst_avi_demux_handle_src_query), (gst_avi_demux_stream_header), (gst_avi_demux_stream_data), (gst_avi_demux_change_state): * gst/avi/gstavidemux.h: Improve A/V sync. Still not perfect. * gst/matroska/ebml-read.c: (gst_ebml_read_seek), (gst_ebml_read_skip): Handle events better. * gst/qtdemux/qtdemux.c: (gst_qtdemux_handle_sink_event), (gst_qtdemux_loop_header), (qtdemux_parse_trak), (qtdemux_audio_caps): Add IMA4. Improve event handling. Save offset after a seek when the headers are at the end of the file so that we don't end up in an infinite loop. * gst/typefind/gsttypefindfunctions.c: (qt_type_find): Add low-priority typefind support for files with no length.
