KongQun Yang 940c3571aa WebMParser: set duration and dts correctly
- dts was not set earlier, although for WebM, we could assume that
  dts is the same as pts.
- Calculate block duration with the difference with the next block
  if duration is not encoded, even if track default_duration is set.
- Use track default_duration as a duration estimate for the last
  block.
- This also removes opus duration computation from encoded data.

Issues #67, #68

Jacob Trimble d1d75f477c Add encryption support to WebM.
This does not support key-rotation and will give an error.  This is
because WebM does not have a way to indicate a change in key ID using
media segments.

language if it's not empty.  Fixed the packager tests for that.
