Summary:
There were 2 recent reports about "visibleheads" not being enabled.
Previously, to enable visibility, one has to run a `pull` command with
`visibility.automirate=start` and `visibility.enabled=true`, and
`pull.automirate=true`, and our current config does not have
`visibility.automigrate`.
There are other issues with pull-based auto migration. For example, the edenfs
backing repo does not run pull and won't be migrated.
Move the visibility and dirstate automigrate logic to `repo.__init__` so they
always run. Also simplify the configuration so a single config
`visibility.enabled=true` (or `format.dirstate`) is enough to trigger the
migration.

Pure Python generator has a few limitations:
- Can only be iterated once.
- Cannot be iterated by multiple threads concurrently.
By converting revset iterators to Rust Stream, they run in different threads

Even if ui.threaded is off, we're seeing sys call interrupt issues. I
think this is because ui.threaded defaults to true, and we check it's value
before loading the repo config (which includes the dynamicconfig to turn it
off). It's already off in dynamicconfig, so let's turn it off by default.
This highlights an issue with dynamicconfig, in that it can't deploy pre-repo

from child processes we spawn (possibly the dynamicconfig child process).

Summary:
This reverts D24066918 (a684e53a31). That diff changed the phabstatus code to use the last
created revset iterator rather than the first for peekahead purposes.
The first revset iterator does appear to be the correct one to wrap. After
D24066918 (a684e53a31) I consistently see `hg log -r 'draft()' -T'{phabstatus}\n'` make
Phabricator queries for only one diff at a time. Reverting the changes from
that diff fixes the issue.
Note that the revset argument passed to `hg log` appears to make a difference
in the behavior here. When using simple revsets including just specific
commit ranges then the peekahead behavior works as expected both before and
after D24066918 (a684e53a31). However, when using `draft()` in the revset specifier then
the behavior works before D24066918 (a684e53a31), but not after it.

features of HG on tests based on the name of the test. Mononoke's integration
tests suit reuses eden/scm's tests suit and as a consequence it triggers the
same `features.py` logic. It was fine until D24201934 (f5988c415c) introduced a feature for
test that is named in the same way as one of the Mononoke tests - the
`test-clienttelemetry.t`.
In order to fix this problem Mononoke will pass a `--nofeatures` flag to the
`eden/scm/run-tests.py` invocations that will turn off the usage of
`features.py`.

Summary:
If Phabricator takes more than 10 seconds to respond, a `socket.timeout`
exception may be thrown. Treat this like other networking errors, and simply
report the diff phabricator status as `Error`. Previously this exception was
unhandled, causing the entire command to abort.

Summary:
This change introduces two new metadata types, Category and Transience, and a mechanism for Category to provide a default Fault and Transience, which can be overriden by the user.
Also introduces a mechanism for attempting to log exceptions which occur during exception logging, falling back to the previous behavior of just swallowing the exception on failure.

Summary:
It only has benchmark code that led to the use of mincode. Now hgcommits is the
main crate for commit storage. `commitstore` without `hg` in its name was
initially planned to support other kinds of commits including git and bonsai.
However we don't have immediate goal for that at present. So let's just remove
the commitstore directory.

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:
This will allow Eden to control what data is in Mercurial's memory and
what is on disk. This will let it persist the hg_import_helper process longer,
and prevent slow startup times when needing to restart it.

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.
