c626e90fda matroskademux: pull mode non-cue seeking
That is, in files that have no index (Cue), perform seek by scanning for
nearest cluster with timecode before requested position.  Scanning is done
as a combination of interpolation and sequential scan.

Fixes #617368.

21c84e23e8 matroskademux: refactor delta unit handling
This allows us to skip delta units earlier and is a bit clearer in my
opinion. It also makes only video buffers ever be delta units, not
just for SimpleBlock as before.

b2ff8042d3 matroskademux: Ignore keyframe flag for non-video streams
When the keyframe bit of SimpleBlock Flags wasn't set, the buffer was being
marked with GST_BUFFER_FLAG_DELTA_UNIT, causing all buffers to be skipped
after a seek. This may be a problem with the Sorenson Squish encoder, but
arguably the keyframe bit should only be applied to video.

Fixes bug #620358.

3d876d2b16 matroska: use the uint64 scaling functions
In demuxer and muxer use the gst_util_uint64 scaling functions rather than
standard integer division. Add warnings (to be changed to debug) for debugging
the timestamp and duration.

80926a5596 matroskademux: skip buffers before a late keyframe (QoS)
Before, vp8dec had no option but to decode all frames even if some/all
of them would be late. With this change, performance when keyframes are
frequent is helped a great deal. On my Thinkpad X60s, decoding a 20 s
1080p sunflower encode with keyframes every 10 frames went from taking
42 s with 5 frames shown to 21 s with 15 frames shown (still slow
enough to count by hand). When keyframes are more sparse, you will
still be able to catch up eventually, but the results won't be as
noticable.

9610c7f354 matroska: handle matroska and webm doctype versions equally
The original plan was to let WebM v1 be the same as Matroska v2 (with
extra constraints), but for simplicity it was decided to handle the
versions equally, such that e.g. SimpleBlock is only allowed in WebM v2.

081f2d00aa matroskademux: Verify lace size in _parse_blockgroup_or_simpleblock
Failure to do this for corrupt input can cause a subbuffer bigger
than the actual buffer to be created, quickly leading to segfault.

ad71d43f52 matroskademux: Advance sparse streams only as much as required to keep the gap smaller than 500ms
Changing it to the newest timestamp that was ever pushed will
increase the segment start in 500ms jumps, which could be just
after the next sparse stream buffer. E.g.

Video at 1.0s, sparse stream at 0.5s would jump the
sparse stream to 1.0s. Now a new sparse stream buffer could
appear that has a timestamp of 0.9s and this would be
dropped for no good reason because of bad luck.
