WebRtcVideoChannel encoder fallback.

Browse Source 
In this CL:
 - Added WEBRTC_VIDEO_CODEC_ENCODER_FAILURE return code that can
   be returned by the encoder wrapper in case of a broken encoder.
 - Added EncoderFailureCallback interface that can be called
   to request encoder fallback to be performed. Implemented by
   WebRtcVideoChannel and called from the VideoStreamEncoder.
 - Updated SelectSendVideoCodec to select all compatible codecs instead
   of just one.
