Kongqun Yang d501b457d0 Fix WebM keyframe detection in BlockGroup

is to look for the absence of the ReferenceBlock element [1].

Jacob Trimble f9bf197f2b Fix bug in VPx codec configuration.
Before, we converted the WebM configuration to MP4 in the video
client, however this lead to a bug when fields were missing.  So
now don't convert until the cluster parser so the extra info from
the stream can be added.

This also fixes a bug where the value was not printed in the warning
logs.

Jacob Trimble abb1abf5c5 Rename StreamInfo::extra_data to codec_config.
Since the |extra_data| field contains codec-specific configuration
data, it makes sense to call it |codec_config|.

KongQun Yang 2c3aed4842 Handle possible NewSampleEvent before ParserInitEvent
For WebM contents, it is possible that we may receive some NewSampleEvent
before receiving ParserInitEvent. This is because init event is fired
after analyzing a video block which could come after an audio block.

Also modified Flush() function to return a bool to indicate whether the
the flush is successful and whether the samples are handled correctly.

And added macro to ensure Flush() and Parse() results are handled.

Fixes #71

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.
