exchange: add fast path for subrepo check on push
Try to check if .hgsub and .hgsubstate exist at all before looking
for them in every changeset to be pushed. The latter can be quite
expensive for large repositories and the existance check is almost free.

simplemerge: make merge_groups() yield only 2-tuples
`merge_groups()` currently yields 2-tuples or 4-tuples, making the
callers check the first element to decide how to interpret the
rest. Let's make it yield only 2-tuples, thereby simplifying life a
little for the callers.

rhg: desambiguate status without decompressing filelog if possible
When status is unsure based on `stat()` and the dirstate if a file is clean
or modified, we need to compare it against the filelog.
This comparison can skip looking at contents if the lengths differ.
This changeset optimize this further to deduce what we can about the length
if the filelog without decompressing it or resolving deltas.

rhg: RevlogEntry::uncompressed_len is signed

rhg: Expose FilelogEntry that wraps RevlogEntry
This can be later extended to access metadata such as `uncompressed_len` without
necessarily resolving deltas.

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.

Simon Sapin <simon.sapin@octobus.net> [Tue, 21 Dec 2021 15:57:30 +0100] rev 48540
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`.
