WebAudio: Add IIRFilterNode

Add a new node, IIRFilterNode, that implements a general IIR filter. The coefficients are fixed at creation and not changeable with no automation functions allowed.


The general idea of an IIRFilterNode has been agreed upon in the W3C WebAudio WG. The exact specification of the node is being reviewed. Implementation will, of course, match the final specification.
