Perform all mixing for an audio input in a single mix operation (instead of a two step polyphony mixdown (by connections) and connections mixdown (by ports)).
Speed up and inline AudioBuffer::accumulate, to speed up mix().
Remove local buffer from Connection (always mix into destination InputPort's buffers).
