Alex Loiko b4977de306 Receive-side ready for multiple channels.
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.
