Currently there are two structs that are identical and track extension details: webrtc::RtpExtension cricket::RtpHeaderExtension The use of the structs is mixed in the code to track the extensions being supported. This results in duplicate definition of the URI constants and there is code to convert between the two structs. Clean up to use a single RtpHeader throughout the codebase. The actual location of RtpHeader may change in future (perhaps to be located in api/). Additionally, this CL renames some of the constants to clarify Uri and Id use.
