This handles the case where Shutdown() is called after Unlink()
(but before the destructor).

- Current source code for vtt.js can be found at:
https://github.com/andreasgal/vtt.js
- vtt.js code taken from commit 6bca57d265fc58cff091148b426ec69f576057d7.
- 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.

rename : content/media/WebVTTLoadListener.cpp => content/media/WebVTTListener.cpp
rename : content/media/WebVTTLoadListener.h => content/media/WebVTTListener.h
- Remove left over references to WebVTT C parser in TextTrackCue and
WebVTTListener classes.
- Remove miscellaneous unused code as well and included libraries as
well.
Copy the periodicWave data into a shareable buffer.
Add a SetBuffer call to send the buffer data to the
OscillatorNodeEngine. Call into blink's PeriodicWave
implementation to generate bandlimited tables bracketing
the desired frequency and interpolate the output data
from them.
Change the PeriodicWave constructor to only take one
length, since both arrays must be the same size.
Change OscillatorNode's SetType to throw INVALID_STATE
instead of NOT_IMPLEMENTED if js tries to assign
type = 'custom' directly.

This is the original code from blink svn trunk r157670 for reference.
This commit has no porting or build support, to make subsequent changes
easier to identify.

Currently FFTBlock only holds the complex frequency domain data
internally, reading and writing to external time domain data
buffers. For PeriodicWave we need to create a real, time domain
signal from real and imaginary frequency domain data. This method
does this without touching the internal output buffer at all.
FFTBlock is just used as a wrapper for kiss_fft_cfg.

This is an equivalent, C-only implementation of blink's
VectorMath::maxmgv or Apple's vDSP_maxmgv. It finds the
maximum absolute value of the elements in a float buffer.
Used by blink's PeriodicWave implementation for normalization.
AudioNodes that keep playing or tail-time references need to have these
references cleared when an AudioContext has completed or is shut down by the
window.
Storing references on the AudioContext instead of on the AudioNodes will allow
the AudioContext to report playing references to the cycle collector until
offline rendering starts for bug 914033. This is not necessary for tail-time
references, but it is tidier to use the same code for playing and tail-time
references.

Following up with the changes made in http://dev.w3.org/html5/webvtt/#dfn-dom-vttcue-vertical, this patch comes to create a new enum to validate and control the possible values for TextTrackCue::Vertical. Throwing behavior was removed for spec conformance.
