Original commit message from CVS: * gst/matroska/matroska-demux.c: (gst_matroska_demux_add_stream), (gst_matroskademux_do_index_seek), (gst_matroska_demux_handle_seek_event), (gst_matroska_demux_parse_blockgroup_or_simpleblock): * gst/matroska/matroska-ids.h: Set DISCONT flag on first buffer after a discontinuity. Fix newsegment events sent when seeking and honour KEY_UNIT seek flag. Create pad with bogus caps if we don't recognise the stream codec id. * gst/matroska/matroska-demux.h: Fix GObject macros.
