Split FlexFEC field trial in two.
- The "flexfec-03" codec is advertised in the SDP whenever the
"WebRTC-FlexFEC-03-Advertised" field trial is enabled.
- Sending FlexFEC packets is enabled whenever the "flexfec-03" codec is
negotiated, and the "WebRTC-FlexFEC-03" field trial is enabled.
After this CL, the number of calls to
WebRtcVideoChannel2::WebRtcVideoSendStream::SetCodec during renegotiation
will be reduced for cases when only one endpoint has the "WebRTC-FlexFEC-03"
field trial enabled.
