4ec5ce6398 Bug 880601. Emulate a form of keyframe skipping by allowing MediaOmxReader::DecodeVideoFrame to decode more than one video frame if video decoding is falling behind. r=cpearce 
If we don't support this in any way, then we get into trouble when there is
plenty of compressed data buffered but for some reason video decoding falls
behind (maybe there was a short period where the video data wasn't available).
Audio playback continues normally, but MediaOmxReader keeps making one call
to ReadAudio and one to ReadVideo, and if each call to ReadAudio decodes at
least as much as the calls to ReadVideo, video decoding can never catch up
to the current audio playback position. So video never plays. And when the
video decoding point gets far enough away from the audio decoding point,
horrible things start to happen, such as video and audio reading completely
different parts of the media cache and interfering with the caching mechanism
(which assumes audio and video reads are close together).

This patch approximates keyframe skipping, and is basically just a way for
MediaOmxReader::DecodeVideoFrame to decode more than one frame at a time
if we need video decoding to catch up.

To prevent pathological situations, we cap both the maximum number of frames
decoded per DecodeVideoFrame and the amount of time we spend in the method
(excluding the time for the last frame).

This patch enables "LOADING", "LOADED" and "ERROR" readiness states to be
applied to the Parent HTMLTrackElement, in order to avoid test flakiness,
and to comply with the HTML5 draft

f5b7023a3b Bug 881475 - Drop cues with malformed timestamps. r=rillian 
The parsing specification requires the UA to drop
cues containing malformed cue-times.
(http://dev.w3.org/html5/webvtt/#dfn-collect-a-webvtt-timestamp)

The OnReportError callback has been modified to notify the parser
that we need need to drop such cues which are deemed 'malformed'
according to the timestamp parsing rules.

2e533bea4f Bug 815643 - Part 6: Optimize FFTBlock to avoid recreating kiss_fftr_cfg objects all the time; r=roc 
Setting up the FFT tables turns out to be quite expensive because of the
large number of calls to sin() and cos().

In the future we may want to look into having a global cache of FFT
tables per size, in order to pay the cost of setting each one of them up
only once.
