matroskadec: set default duration for simple block
...
When a normal Block is parsed, duration is initialized to
AV_NOPTS_VALUE. If it is not changed, then the track's default
duration is used. But for SimpleBlock, duration is initialized to
0 instead of AV_NOPTS_VALUE. This is due to the difference in how
EBML_NEST vs EBML_PASS are processed. Setting duration to 0 leads
eventually to wrongly estimate the frame duration in util.c

matroskadec: add generic element length validation.
...
This validate the length of a mkv element directly after reading
it.
This has the advantage that it is easy to add new limits and makes
it less likely to forget to add checks and also avoids issues like
bits of the length value above the first 32 being ignored because
the parsing functions only takes an int.
Previously discussed in the "mkv 0-byte integer parsing" thread.
