This change essentially divides AudioCodingModuleImpl into two parts: one is the code related to managing codecs, now moved into CodecManager, and the other is what remains in AudioCodingModuleImpl. This change also removes AudioCodingModuleImpl::InitializeSender. The function was essentially no-op, since it was always called immediately after construction.
