Summary:
On the hg servers we're seeing crashes due to signals during syscalls.
Rolling back to prior to the signal changes seems to have fixed it, though we
haven't bisected enough to be sure this is the cause.
The ui.threaded option is already used to opt-out of running on a background
thread, let's also use it to opt-out of the custom signal registering in hopes
that it fixes the server issue, until they can be deprecated.

Summary:
Since D23247941, .clang-format is no longer behind a symlink, which means that
we can get clang-format niceness on Windows without having our own
.clang-format file.
Thus, let's just remove eden/scm/.clang-format

Summary:
Add predicate based PutBehaviour logic to manifoldblob.
This will prevent overwrites of keys when in IfAbsent mode, and will generate useful logging in OverwriteAndLog and IsAbsent mode.
This change factors our part of the put logic to put_check_conflict, so that it can use re-used from each of the PutBehaviour cases.

This will allow Eden to control what data is in Mercurial's memory and

Summary:
This was added in D16078908 (1bc6ecf8fe). It turns out fsync followed by a hardlink
on btrfs results in very slow hardlink performance (100-600ms). Since fewer and
fewer of our files use this atomic write code path and since this affects almost
every hg write command, let's roll this back.
This will increase the chance of data loss during a hard reboot, but commit
cloud is good enough to allow recovering from that in almost every situation.

Summary:
From an OSS perspective, I think that the log tables have a place. However for
daily use perspective, next to scuba they don't add much except retention and
instead feel more heavy weight to manage. This change probably simplifies
things and makes the Segmented Changelog component easier to maintain.

Summary:
This diff is a first step in a preparation for removing Preserved state from
CommitSyncOutcome. It does two things:
1) Remove unsafe_preserve_commit method and instead rewrite commit with noop
config version - this is exactly how we are going to do it in production
2) While there also select correct mover for validation - previously we were
always picking the current mover
I've also added a bunch of print statements, since it was tricky to debug what
was going on in the test.
