This CL adds the ability to configure RTPSender to include the MID header extension when sending packets. The MID will be included on every packet at the start of the stream until an RTCP acknoledgment is received for that SSRC at which point it will stop being included. The MID will be included on regular RTP streams as well as RTX streams.
