Summary:
Now that all our repos are treemanifest, let's enable the extension by
default in tests. Once we're certain no one needs it in production we'll also
make it the default in core Mercurial.
This diff includes a minor fix in treemanifest to be aware of always-enabled
extensions. It won't matter until we actually add treemanifest to the list of
default enabled extensions, but I caught this while testing things.

Summary:
This hardcodes several perftweaks configs that have been enabled for major FB
repos for months:
[perftweaks]
disablebranchcache = True
disablebranchcache2 = True
disableresolvingbranches = True
disableupdatebranchcacheoncommit = True
Practically, this means the branchmap is now just `{'default': heads}`. (i.e.
there are no named branches other than `default`), and branchcache is removed
(i.e. `.hg/cache` does not exist without clindex or in-repo tags).
This diff only makes easy-to-verify logic changes by assuming the configs and
removing dead code. Things can be further cleaned up. They will be done by
upcoming changes.
Most test changes are due to the fact that `.hg/cache` is no longer created.

Summary:
Migrate away from using the "hg branch" command to "hg commit --extra branch="
instead. In the future the branch namespace would be removed, so we create
local tags instead.
`test-revset2` was split from `test-revset` and has the same header. Do the
same change to it. Besides, de-duplicate tests about the `tag()` revset.

Summary:
D13853115 adds `edenscm/` to `sys.path` and code still uses `import mercurial`.
That has nasty problems if both `import mercurial` and
`import edenscm.mercurial` are used, because Python would think `mercurial.foo`
and `edenscm.mercurial.foo` are different modules so code like
`try: ... except mercurial.error.Foo: ...`, or `isinstance(x, mercurial.foo.Bar)`
would fail to handle the `edenscm.mercurial` version. There are also some
module-level states (ex. `extensions._extensions`) that would cause trouble if
they have multiple versions in a single process.
Change imports to use the `edenscm` so ideally the `mercurial` is no longer
imported at all. Add checks in extensions.py to catch unexpected extensions
importing modules from the old (wrong) locations when running tests.

Summary:
Move the `predecessors` and `successors` revsets to core, and unify the
variants as a single revset.
Before:
* `predecessors` (provided by fbamend) only returned the immediate
predecessors.
* `successors` (provided by core) returned the given commit and all eventual
successors.
* `allpredecessors` and `allsuccessors` (provided by fbamend) returned all
eventual predecessors and successors, not including the original commit.
Now all these revsets work like the old core `successors`, and additionally
have `depth` and `startdepth` parameters which can be used to customize the
behaviour. This makes them analogous to `ancestors` and `descendants`.
To maintain compatibility with existing users of `allpredecessors` and
`allsuccessors`, these revsets default to a start depth of 1, so they
do not include the original commits.

Summary:
Be more permissive about spaces. Namely:
- Spaces after a section name like `[foo] ` are allowed.
- Spaces in config names are allowed.
- Spaces at trailing lines are ignored and no longer insert an `\n` to the previous config.
This makes it closer to the older config parser behavior. But it's still
different on some cases, like `[foo]]`, `[foo] # bar`, `[foo]]` still do not
parse.
Benchmark shows no obvious (within 10%) slowdown. So this is probably fine.

Summary:
Switch `ui.load` and `ui.readconfig` to use the Rust config parser.
`ui` now no longer depends on `config.config` or `rcutil`.
Pest's error messages are fancier, thus most test changes.
For the fbsource repo, debugshell shows the new code is 10+x faster:
On laptop:
Before:
In [1]: %timeit m.ui.ui.load()
10 loops, best of 3: 27.8 ms per loop
After:
In [1]: %timeit m.ui.ui.load()
100 loops, best of 3: 1.85 ms per loop
On devserver:
Before:
In [1]: %timeit m.ui.ui.load()
100 loops, best of 3: 16.8 ms per loop
After:
In [1]: %timeit m.ui.ui.load()
1000 loops, best of 3: 1.28 ms per loop
Since `ui._rcfg` is no longer copy-on-write, there is concern about `ui.copy()`
performance. It is faster too (on devserver):
Before:
In [1]: %timeit ui.copy()
1000 loops, best of 3: 198 µs per loop
After:
In [1]: %timeit ui.copy()
10000 loops, best of 3: 157 µs per loop
The old `ui.py` was copied to `legacyui.py` and can replace the new `ui.py` if
a config file exists on the system. This provides a way to switch back to the
old config parser in case of emergency.

Summary:
The helper could be used in individual tests to enable chg if chg exists.
This allows us to have more precise control on what tests to use chg instead
of using a global flag in run-tests.py.
This makes certain tests containing many hg commands much faster. For example,
`test-revset.t` took 99 seconds before:
% ./run-tests.py test-revset.t --time
.
# Ran 1 tests, 0 skipped, 0 failed.
# Producing time report
start end cuser csys real Test
0.000 99.990 86.410 12.000 99.990 test-revset.t
And 10 seconds after:
% ./run-tests.py test-revset.t --time
.
# Ran 1 tests, 0 skipped, 0 failed.
# Producing time report
start end cuser csys real Test
0.000 10.080 0.380 0.130 10.080 test-revset.t
Also enable it for some other tests. Note the whitelist is not complete. We
probably want to whitelist more tests in the future.
The feature could be opted out by deleting `contrib/chg/chg`.

We keep the new option in the 'experimental.evolution' namespace in order to

systems under load (like if we're running all the tests in parallel). This patch
