gst/matroska/matroska-demux.c: Handle codec_data for VfW compatibility codec IDs (#339451)

Browse source 
Original commit message from CVS:
Patch by: Mark Nauwelaerts  <manauw at skynet dot be>
* gst/matroska/matroska-demux.c: (gst_matroska_demux_video_caps):
Handle codec_data for VfW compatibility codec IDs (#339451)
* gst/matroska/matroska-mux.c:
(gst_matroska_mux_video_pad_setcaps):
Same here, handle codec_data and add additional caps we can handle
now to the pad template (huffyuv, dv and h263 video) (#339451)
