These structs will be used for ORTC objects (and their WebRTC equivalents). This CL also introduces some minor changes to the existing implemented structs: - max_bitrate_bps uses rtc::Optional instead of "-1 means unset" - "mime_type" turned into "name"/"kind" (which can be used to form the MIME type string, if needed). - clock_rate and channels changed to rtc::Optional, since they will need to be for RtpSender.send(). - Renamed "channels" to "num_channels" (the ORTC name, which I prefer).
