Add realaudio/realvideo support

Looks good to me, you even care about the codec data :)

Oh, forgot to mention something. That mdpr_data is the whole chunk of extra_data contained in a realmedia stream (which needs to be extracted by rmdemux).

The reason why I did that is because not all information contained in a mdpr is not parsed/extracted by rmdemux into individual caps information.

Extraction of it in rmdemux allows you to be able to *transmux* from a rm container to a mkv container, but wouldn't allow you to encode realaudio/realvideo streams that come from a non-rm container.... but i think the first case is the main reason you'd want to use real-in-matroska.

	* gst/matroska/matroska-demux.c: (gst_matroska_demux_send_event),
	(gst_matroska_demux_video_caps), (gst_matroska_demux_audio_caps):
	* gst/matroska/matroska-mux.c:
	(gst_matroska_mux_video_pad_setcaps),
	(gst_matroska_mux_audio_pad_setcaps), (gst_matroska_mux_finish):
	Add Real[Audio|Video] support to Matroska containers.
	It works fine for:
	* decoding real audio/video streams contained in mkv
	* 'transmuxing' real (.rm) files into .mkv files
	It will not work though for encoding real[audio/video] streams that
	don't contain the 'mdpr_data' extra data on the caps.
	The reason why this will not work is because I never intended to
	duplicate virtually all the 'mdpr' block creation into mkvmux.
	Fixes #536067
