Robert O'Callahan fc44cd635c Bug 804837. Part 0: Rework the connection and input/output port logic for Web Audio nodes; r=ehsan
Here's what this patch does:
-- Makes AudioNodes mostly not use nsWrapperCache. AudioDestinationNode
still does.
-- Rename MaxNumberOfInputs/Outputs to NumberOfInputs/Outputs, and have them
default to 1 in AudioNode.
-- Allow any number of nodes to be connected to any given input/output port.
