Summary: The inline revlog format merges `.i` and `.d` into one `.i` file. It was intended to reduce the number of files for filelogs. For the changelog one extra file does not hurt. This makes it easier to write native code parsing the changelog revlog index. Reviewed By: xavierd Differential Revision: D17125922 fbshipit-source-id: f48ffe0d2df71abec007a80e05b684dcbac71883
