* Update vtt.js to the newest version which has the capability
of reporting back ParserErrors.
* Update the update-vtt.js script a bit as well since
the symbols that it exports have changed a bit since the last import.
Some of the general information it outputs has since changed as well
like where the repo exists.
* Update WebVTTListener to set the track readiness state
to 'failed to load' if the WebVTT file is not loaded correctly.
- This allows us to pass around ReadyState values. It also makes the type
explicit which will save us from potentially shooting ourselves in
the foot.
- I also renamed 'READY_STATE_NONE' and 'READY_STATE_ERROR' to
'NotLoaded' and 'FailedToLoad' respectively in the enum. This is to
avoid some name collision errors we were having. It also makes it more
clear where in the spec this is as these names are the spec's names
for the TextTrack enum.
This makes more sense as the READY_STATE values in the spec are always
referred to be 'text track readiness states' not HTMLTrackElement
readiness states.
- These two parts of the spec were recently removed as they
were seen as unecessary or bad design, in the case of the
VTTRegion TextTrack extensions. See the spec bug at:
https://www.w3.org/Bugs/Public/show_bug.cgi?id=24380
- Added vtt.js, a JS WebVTT parser, to Gecko.
- Added a wrapper to interface between it and Gecko.
- Updated TextTrackCue and WebVTTListener to work with it.
