This ensures a test can make such a request, receive the event that the
load has been suspended, and cancel the request, all before the load has
completed.

Report that we can play MP3 inside MP4 on Windows Vista and later in
HTMLMediaElement.canPlayType. Chrome and IE on Windows match this behaviour.
Add a test file with MP3 contained inside MP4. Note the B2G emulator can't play
this file, so I added a codecs parameter to the file's mime type so that
decoder backends have to opt-in to testing with it.
Enable playback of MP3 inside MP4 in WMFReader.
Change from reporting the IMFSourceReader's duration inside WMFReader, to
instead report the IMFSourceReader's duration as the media "end time". This is
needed because the MP3-contained-in-MP4 file's first sample output by the
IMFSourceReader has a non-zero timestamp, and the MediaDecoderStateMachine
assumes that the media samples will be in the range
[$firstSampleStartTime, $firstSampleStartTime+$reportedDuration]. But that's
not the case here, the IMFSourceReader seems to output samples in the range
[0,$reportedDuration]. This assumption mismatch means on the
MP3-contained-in-MP4 file we end up trying to seek after what the
IMFSourceReader assumes is the end of the file, which fails and causes
test failures.
Implement HTMLMediaElement.fastSeek(), basically by changing all the
MediaDecoderReader::Seek() overrides to not call
MediaDecoderReader::DecodeToTarget(), and have MediaDecoderReader::DecodeSeek()
call DecodeToTarget() if we're doing an accurate (non-fast) seek.
Update gizmo.mp4 to have a keyframe every second, instead of only 1 keyframe at
the start of stream. This makes the unit test I added more useful for mp4...
I pushed most of the seek target clamping logic in MediaDecoder up into
HTMLMediaElement, so that we're clamping in fewer places. Note
MediaDecoderStateMachine::Seek() still sanity checks the seek target.
We have to update the currentTime/MediaDecoder playback position after a seek
completes now, rather than assuming the seek always got it exactly right.
Removed those pesky assertions about seek target lying in the first frame after
seek, since actually sometimes the media doesn't have samples for all streams
after a seek (either due to the media being encoded like that, or because of a
bug in the platform's decoder, not entirely sure).

Bug 778077 - Fix up MediaOMXReader fastseek to ensure audio stream stays in sync with video stream. r=cajbir
The extra null samples were mostly harmless, and may have even helped avoid
bug 983062 sometimes, but caused the "Samples missing" assertion to fail.

This takes care of automatic track selection for tracks with
the default attribute specified. However, it does not take
into account any user preferences set through Firefox such
as default language.
- I've refactored the way we set modes as well, making it a part
of the TextTrack ctors.
- I've also changed TextTracks in the track tests to have their
mode set to 'hidden' in order to be able to call TextTrack::Cues.
This is correct since TextTracks with a mode of 'disabled' do not
return null for their cue lists.
- This implements sorting on the MediaElement's list of TextTracks as
described in: http://www.whatwg.org/specs/web-apps/current-work/multipage/the-video-element.html#text-track-model
This is important as automatically positioned cues will have a line
position that is relative to their TextTrack's position in the
MediaElement's list of TextTracks.
- Added a TextTrackSource enum which all TextTracks have. This helps
distinguish where a TextTrack came from.
