Made path from NetEq to AudioTransport ready for many-channel audio. If there is one stream, we can handle anything that fits in an AudioFrame. For many streams, the current limit is 6. Some multi-channel combinations are not supported: e.g. if we get stereo audio and attempt to play out 6 channels. Changes: * AudioFrameOperations - replaced the MonoTo* and *ToMono methods by UpmixChannels & DownmixChannels. * AudioMixer: removed DCHECKs for <= 2 channels and tweaked the mixing algorithm to handle many channels.
