mSquare, mTriangle, and mSaw are not initialized in the OscillatorNodeEngine
constructor, just like they are not initialized when switching to
OscillatorType::Sine. These parameters are initialized if and when switching
to the OscillatorTypes that use them.
mFinalFrequency, mNumberOfHarmonics, mSignalPeriod, mAmplitudeAtZero,
mPhaseIncrement, mPhaseWrap are not initialized in the OscillatorNodeEngine
constructor, just like they are not initialized immediately on switching
OscillatorType. These parameters are initialized in
UpdateParametersIfNeeded(), conditional on mRecomputeParameters.

This removes the dependence on AllInputsFinished() which didn't return true
for many input types.
The DelayProcessor is no longer continuously reset (bug 921457) and the
reference is now correctly added again when all inputs are finished and then
new inputs are connected.

An OfflineAudioContext needs to keep references to nodes that will be used if
startRendering() is called. If, however, the last reference to the Context is
removed, then startRendering() will not be called and so the nodes will not be
used and can be unlinked now.

Storing references on the AudioContext instead of on the AudioNodes will allow
the AudioContext to report them to the cycle collector until offline rendering
starts.

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

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.
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.
