* split tracks from medias * move tracks into dedicated package * move media into dedicated package * edit Medias.Marshal() in order to return SDP * add medias.Find() and simplify examples * improve coverage * fix rebase errors * replace TrackIDs with MediaIDs * implement media-specific and track-specific callbacks for reading RTCP and RTP packets * rename publish into record, read into play * add v2 tag * rename tracks into formats
