SdpVideoFormat is used to configure video encoder and decoders. This CL adds support for comparing two SdpVideoFormat objects to determine if they specify the same video codec. This functionality previously only existed in media/base/codec.h which made the code sensitive to circular dependencies. Once downstream projects stop using cricket::IsSameCodec, this code can be removed.
