echo-cancel: Add the WebRTC echo canceller

Browse source 
This adds the WebRTC echo canceller as another module-echo-cancel
backend. We're exposing both the full echo canceller as well as the
mobile echo control version as modargs.

Pending items:

1. The mobile canceller doesn't seem to work at the moment.

2. We still need to add bits to hook in drift compensation (to support
   sink and source from different devices).

The most controversial part of this patch would probably be the
mandatory build-time dependency on a C++ compiler. If the optional
--enable-webrtc-aec is set, then there's also a dependency on libstdc++.
