744167056c matroskademux: fix for subtitle buffers with NUL terminators 
Commit 45892ec8 created a regression where g_utf8_validate() would fail
if the subtitle buffer had a NUL terminator as part of the data.

45892ec8be matroskademux: fix trailing '*' displayed with some text subtitles 
The subtitle buffer we push out should not include a NUL terminator
as part of the data, we just add such a terminator for safety, but
it should not be included in the buffer size.

A NUL terminator is not valid UTF-8, so checks will fail if it's
included in the size, and the NUL will be replaced by the fallback
character specified when converting, i.e. '*'.

d56b11af56 matroska: store stream tags and push as updated 
New tags can be found on different parts of the file, so this patch
keeps the stream taglists around for the life cycle of the pad
and adds those new tags as found. Then a new tag is found, the
pad's is marked with a tags changed flag, making the element push
a new tag event on the next check. Before this, we were sending
only the newly found tags, as the element was losing its taglist
when pushing the event.

it is marked as a draft, this part was confirmed to be correct on
IRC), and allows one to determine whether a demuxed stream is
multistream or not, and thus set the multistream caps field
accordingly. In turn, this means downstream does not have to guess.

cf0c780138 matroskaparse: better default caps when none set 
Uses information gathered during EBML parsing to
forge a more suitable set of caps instead of blindly
assuming everything is video/x-matroska.

For consistency, stream type reset was added to
matroska-demux too.

809d105982 matroskademux: Don't skip all video frames until the first keyframe 
Instead do it like all other demuxers and let parsers and decoders
handle that. The keyframe information inside the container might
be completely wrong like in the sample file of the bug report,
and if it is correct and we push no keyframes, then the parsers
and decoders will handle that properly anyway.

f8158baa93 matroskamux: remove obsolete write-dummy-and-overwrite-on-eos code 
The need for rewriting apparently is obsolete 0.10 leftover.
We now have caps for subtitles when we create the headers,
so we always write the correct data in the first place.

1c6ee3fba4 matroskamux: write subtitle codec ID and data at start when known 
This avoids issues with writing dummy data first, then having
to come back and write correct data later. Doing so prevents
the muxed stream from being actually streamable.

7f8c4dceb4 Revert "matroskamux: Use the running time for container timestamps, not buffer timestamps" 
This reverts commit b3aa8755fe.

We are already using the running-time because they were placed on the
buffers with gst_collect_pads_clip_running_time(). Arguably it would be
better to not modify the incomming buffers but collectpads seems to want
to use absolute timestamps from the buffers for finding the best buffer
(this can be changed with a custom compare function..).

b3aa8755fe matroskamux: Use the running time for container timestamps, not buffer timestamps 
Buffer timestamps have no real meaning here, and for selecting the next
buffer we already use the running time anyway.
