Summary:
Turn on rust changelog (changelog2) for all hosts (except hgsql).
Turn on doublewrite backend for hg-dev hosts, triggered by pull.
Tests are mostly working, and I have been using it for weeks.

Summary:
There are 2 issues:
- len(repo) is no longer the "max rev" + 1. Use 1<<63 instead.
- If invalidatelinkrev is a repo requirement, linkrev can no longer be trusted.

Summary:
Add a way to actually try out segmented changelog by setting
`format.use-segmented-changelog`.
The main compatibility issues are assumptions that `0 .. len(repo)` are valid
revision numbers. Segmented changelog uses 2 spans `0 .. len(master_group)`
and `<a large 64-bit int> ..` for the non-master group. Some assumptions
about `len(repo)` were removed.
Segmented changelog also does not support linkrevs since revs can be
re-assigned. Some logic (ex. in treemanifest) that relies on linkrev being
`len(repo)` is changed.
There might be other issues, which will be fixed once we discover them.

Summary:
The Rust strip logic works for both revlog and segmented changelog. Use it in
tests for easier segmented changelog migration.
The old revlog strip has a lot of complexities on linkrev. Since this is only
used for testing, I avoided the complexities by just saying all linkrevs are
invalidated so we can skip the complexities of dealing with filelog or
manifest, or generating a temporary bundle and unbundling them later.
Most test changes are because we no longer strip filelogs. So unbundling
them will not add new file revisions.
`test-repair-strip.t` is removed because it is only about "Permission Denied"
cases. With the new code path file logs are not stripped and the test is not
relevant.
This does not affect hgsql as it has the Rust logic totally disabled.

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