First of all a keyframe seek should be done to the
keyframe right before the requested position and not
to the keyframe that is nearest to the requested position.
Use per track index arrays and use our new binary search function
from core to speed up the search.
Not all Matroska files have a Tags element which contains
information about the title among other things. Most video
Matroska files only contain the Title element so we
should parse this too. Fixes bug #570435.

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.

archive.

(gst_matroska_demux_parse_blockgroup_or_simpleblock):
If the duration of a block is unknown only use the timestamp for the
first lace and use GST_CLOCK_TIME_NONE as duration for the following
laces. Otherwise every lace has the same timestamp which leads to
various problems. Really fixes bug #548831.
Original commit message from CVS:
* gst/matroska/matroska-demux.c: (gst_matroska_demux_add_stream):
Don't calculate the default duration of a frame from the audio sampling
rate. This only works for raw audio if every frame contains a single
sample and results in broken buffer durations for other formats
if no specified default duration is given or the blocks have no
duration. Fixes bug #548831.

This also fixes Matroska files where the first buffer doesn't start
at timestamp 0. Fixes bug #429322.
The duration of a block is the default duration multiplied with the
number of laces. Every lace is one frame and the default duration
is the duration of one frame. This fixes playback of files that use
lacing for some tracks.

Improve debug output everywhere and fix the EOS logic.
Check the values of the ContentEncoding elements more strictly and
don't use tracks for which it's invalid.
Check that the track number is unique for this stream.
Check that seek positions are below G_MAXINT64 as our seeks are
int64-based and overflows will fail badly.
After seeks also don't push SimpleBlocks until the first one
containing a keyframe is found. Before this was done only for normal
Blocks.
