Summary:
The old linear changelog search does not scale and does not work with segmented
changelog, which makes commit data lazy. The "forksearch" is also problematic as
it can produce non-deterministic results. Let's disable the linear search by
default with the intention to remove it if nobody complains.

Summary:
We want to delete all the non-treestate dirstate implementations. Let's
start throwing an exception if treestate is not enabled. We temporarily have a
bypass in case we break an important usecase in the process.
This also sets the standard new repo to be created in treestate mode, but adding
treestate to newreporequirements.
This was landed once as D19204621 but was backed out because eden backing repos
were using the odl formats and hadn't been upgraded. We fixed that, and now the
data shows ~10 people still using repos in this condition
(https://fburl.com/scuba/dev_command_timers/zxb5hsg2). Some of them are broken
repos, some are ancient eden repos and a simple eden rm and eden clone should
fix them, some are simply old non-eden repos that no one has run commands in in a while.

Summary:
During `hg update`, Mercurial forks multiple processes to write files on disk
concurrently, this is done as fetching blobs from the content store, and
writing them to disk is CPU bound. Usually, threads would be the preferred way
of speeding up such process, but unfortunately, Python has GIL that severely
limit the available concurrency. So, multiple processes were chosen.
Unfortunately, the multi-process solution also brings a lot of other issues,
more recently, we've had cases where the connections to the server and memcache
had to be dropped after the fork. In some other cases, this caused deadlocks.
And the solution is not effective on Windows.
Now that Mercurial is getting more and more Rust, we could instead go back to
the threads solution by using them in Rust, and have Python just push work to
them, this is exactly what this change does.
Things that are left to be done, but I wanted to get a diff out first:
- no file path audit
- no file backup
- no symlink creation
- probably other things I'm missing

Summary:
On bad network link (such as on VPN), the reliability of the connection to

Summary:
We've had cases where a git commit goes in that shouldn't be translated
to Mercurial. Let's add an option to skip the commit. Instead of skipping it
entirely (which would require complicated logic to then parent the following
commit on the last converted commit), let's just convert the skipped commit as
an empty commit. This should cover the cases we've encountered so far.

Summary:
We never actually enabled it in production, and our new storage (ex. metalog,
indexedlog) are SIGKILL-safe. Only the changelog (revlog) might be subject to
double Ctrl+C issues. And we have debugfixcorrupt which can fix changelog
corruptions. So nointerrupt becomes less important.
The direct motivation is the test has been too flaky recently (and it's hard to
reproduce locally).

Summary:
This diff marks **ALL** mercurial tests requiring Python 2 feature.
After you fixes some tests, simply remove the `py2` feature requirement and that tests will be continuously run after your diff is landed.
To bypass this feature requirement, run the tests command with `HGTEST_FORCE_PY2=1`. For example:
```
HGTEST_FORCE_PY2=1 buck test //eden/scm/tests:hg_run_tests
```
or
```
HGTEST_FORCE_PY2=1 python run-tests.py
```
----
Basically this diff are created with the following commands:
```
$ sed -i 's/import feature\(.*\)$/import feature\1\n\nfeature.require(["py2"])/' test-*-t.py
$ sed -i '1s/^/#require py2\n/' test-*.t
$ ls | grep -P "^test.*(?<\!-t)\.py$" > list && vim -p $(cat list)
# manually adding feature requires for these Python tests.
```
(Note: this ignores all push blocking failures!)
