Summary:
Switch debugrebuildchangelog from using revlog stream clone to lazy segment clone.
This removes the revlog techdebt and can be used as a way to repair
repos with broken segmented changelog. As we migrate off double-write backend we
can no longer migrate down to revlog then migrate up, and a full reclone can be
slow. So a partial reclone command that just recreates the segmented changelog
seems useful.
This command is one of the two commands that handle emergency situations
when segmented changelog related logic goes wrong. The other command
is the emergency clone mode, added by D27897892 (d1413bbbad), which assumes everything
related to segmented changelog is broken on Mononoke side and we still
need to commit and push. This command relies on segmented changelog
related features, such as hash<->location lookup, and clone on Mononoke
to work properly and the server having a compatible IdMap. So it might
not be able to address all issues if Mononoke goes wrong.

Summary:
Scratch remote bookmarks are considered draft() and were not cleaned up.
Practically there are users with 100+ scratch remote bookmarks. Let's
clean them up too.
Note the commit still remain visible, which will be fixed in upcoming
diffs.

Summary:
The `notbackedup()` revset is used as part of `summary` that prints information
at the end of `smartlog`. It can take hundreds of milliseconds if there are
many heads. Detect segmented changelog and use a fast path for it.
Practically this reduces `summary` from 594ms to 91ms for me:
With segmented changelog (doublewrite backend) and new code path:
91 \ summary status.py:23

Summary:
In preparation for merging fb-mercurial sources to the Eden repository,
move everything from the top-level directory into an `eden/scm`
subdirectory.
