Periodically update channel parameters and send TargetBitrate message.

Currently, parameters are periodically updated, but the TargetBitrate
message is only sent if a new bitrate is set. It should be sent
periodically to indicate the signaled bitrate is valid and to prevent
stale values due to loss of RTCP packets.
