filelog: add a comment explaining a fast path in filerevisioncopied() Differential Revision: https://phab.mercurial-scm.org/D11964

rhg: Store p1, p2, and hash in RevlogEntry This avoids a duplicate index lookup Differential Revision: https://phab.mercurial-scm.org/D11963

rhg: RevlogEntry::uncompressed_len is signed The corresponding Python code appears to explicitly check for non-negative values. Differential Revision: https://phab.mercurial-scm.org/D11962

rhg: Expose FilelogEntry that wraps RevlogEntry This can be later extended to access metadata such as `uncompressed_len` without necessarily resolving deltas. Differential Revision: https://phab.mercurial-scm.org/D11961

rhg: Add RevlogEntry::data that does delta resolution This requires keeping a `&Revlog` reference inside the `RevlogEntry` struct. This struct already had the appropriate lifetime parameter. Differential Revision: https://phab.mercurial-scm.org/D11960

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`.
