Subject: Introduce a sh_common struct that contains the parts in common by the
 audio, video and sub "stream headers". One reason for this is to help
 avoid/make more obvious things like members with the same function but
 different name (extradata vs. codecdata etc.), or members with the same name
 but different semantics (pts for audio vs. pts for video).
