Add logs to about:webrtc to pin down what's going on with the "robotic voice" reports. In particular, I'd like to capture on the receiving side: (1) the input to the decoder, (2) output from the decoder, (3) output of NetEQ (where it goes into media pipeline) -- and on the sending side, I'd like to capture (1) the input into the encoder and (2) output from the encoder (in case it's an encoding issue). This would initially be a capture snap-shot to one or more sample log files triggered from a button on the about:webrtc page. The length of the capture and file creation would be controlled by software. Auto-uploading of the created log files may be also be initiated once capture is complete.

Mass change P2->P3 to align with new Mozilla triage process.
