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.

This is needed to remove self-references in the graph when no more processing
will take place on the graph.

This means that the graph will be shutdown properly, even if the
AudioDestinationNode is unlinked before AudioContext::Shutdown() is called.
Making MediaStreamGraph::DestroyNonRealtimeInstance() idempotent also makes
AudioContext::Shutdown() idempotent.

The azimuth calculation in the Web Audio spec becomes undefined in this
situation as it requires normalizing a zero vector. The panning effect should
not depend on azimuth when the source is directly above the listener (because
position does not depend on azimuth), but the specified "equalpower" panning
model does depend on azimuth even at this elevation. Setting azimuth to zero
produces the same result as if the normalized projection were replaced with a
zero vector.
