7a8ebc4a79 matroskamux: reduce newsegment event spam and set discont flag where needed 
Only send newsegment events with new positions downstream when actually
needed, instead of sending multiple newsegment events with new seek
positions in a row. Also set the discont flag on buffers after a
discontinuity.

84e47e579b matroskamux: set correct buffer offsets after seeks 
Re-use the existing 'pos' field maintained by ebml writer to set
buffer offsets. This also makes sure that we set the right offsets
on buffers after a seek (e.g. when writing an index at the end).

13b553bce7 matroskademux: attempt more resync upon (cluster) parse error 
That is, if parse error occurs in state requiring to move to next cluster,
and doing so to the expected next position of cluster fails, then scan for a
next cluster from present position and resume from there.

e49c31fd25 matroskamux: revert change that set a reserved flag on the Block. 
So matroska's Block structure has no keyframe flag, only the SimpleBlock has it.
To detect keyframes in Blocks, it is just the BlockGroup container that needs
to have a ReferenceBlock attached if it is a delta frame in video.

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.

Philip Jägenstedt
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.

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.

Old gst_ebml_read_ascii renamed to gst_ebml_read_string, also used by

as gst_ebml_read_ascii is used for reading doctype and codec id and we
might just as well give up early in those cases.
