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:
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.

These are some simple cases. More to come in a future change.

Now that the 'vfs' classes moved in their own module, lets use the new module
directly. We update code iteratively to help with possible bisect needs in the
future.
smartset sorting is lazy (so faster in some case) and better (informs that the
set is sorted allowing some optimisation). So we rely on it directly.
Some test output are updated because we now have more information (ordering).
The main goal of this patch series is to reduce the use of PyXxx() function
that is likely to require ugly error handling and inc/decref. Plus, this is
faster than using PySet_Contains().

This patch ignores out-of-range roots as they are in the pure implementation.
Because reachable sets are calculated from heads, and out-of-range heads raise
IndexError, we can just take out-of-range roots as unreachable. Otherwise,
the test of "hg log -Gr '. + wdir()'" would fail.
"heads" argument is changed to a list. Should we have to rename the C function
as its signature is changed?
Though PyInt_AS_LONG() can return a value no matter if it isn't an int object,
it could exceed the boundary of the underlying struct. I think C API should be
defensive to such errors.
Before this patch, release_seen_and_tovisit did not return NULL, so the
exception was not raised immediately. As Py_XDECREF() and free() are safe
for NULL, we can simply bail in any case.
If revlog file is corrupted, it can have parent pointing to invalid revision.
So we should validate it before updating nothead[], phases[], seen[], etc.
Otherwise it would cause segfault at best.
We could use "rev" instead of "maxrev" as upper bound, but I think the explicit
"maxrev" can clarify that we just want to avoid possible buffer overflow
vulnerability.
Many tests didn't change back from subdirectories at the end of the tests ...
and they don't have to. The missing 'cd ..' could always be added when another
test case is added to the test file.
This change do that tests (99.5%) consistently end up in $TESTDIR where they
started, thus making it simpler to extend them or move them around.
