rhg: Rename some revlog-related types and methods
Use "data chunck" and "data" for a revlog entry’s data before and after
resolving deltas (if any), repsectively.
The former `FilelogEntry` actually only contains data, rename it to
`FilelogRevisionData` accordingly. This leaves room to later have a
`FilelogEntry` type that wraps `RevlogEntry`.
