Summary:
Turned on the auto formatter. Ran `arc lint --apply-patches --take BLACK **/*.py`.
Then run `arc lint` again so some other autofixers like spellchecker etc. looked
at the code base. Manually accept the changes whenever they make sense, or use
a workaround (ex. changing "dict()" to "dict constructor") where autofix is false
positive. Disabled linters on files that are hard (i18n/polib.py) to fix, or less
interesting to fix (hgsubversion tests), or cannot be fixed without breaking
OSS build (FBPYTHON4).
Conflicted linters (test-check-module-imports.t, part of test-check-code.t,
test-check-pyflakes.t) are removed or disabled.
Duplicated linters (test-check-pyflakes.t, test-check-pylint.t) are removed.
An issue of the auto-formatter is lines are no longer guarnateed to be <= 80
chars. But that seems less important comparing with the benefit auto-formatter
provides.
As we're here, also remove test-check-py3-compat.t, as it is currently broken
if `PYTHON3=/bin/python3` is set.

Having to constantly adjust these is a hassle. It's easy for this to slip by
when not testing on Windows, and then when it happens on stable, the tests fail
for the next 3 months if we follow the rules for stable.
This works the same way the EOL differences are ignored, namely to adjust on the
fly and recheck on Windows. I can't think of any situation where there would be
a '\' on Windows, a '/' elsewhere, and the '/' should be considered a failure on
Windows.
This fixes the obvious output problems where (glob) is missing. Without this,
test-alias.t, test-remotenames.t and test-largefiles-misc.t are failing. The
flip side (not handled by this) is the case where an unnecessary glob is
present. There seems to be two separate behaviors. f3517e22bfa1 is an example
of where the test has been autocorrecting (with output differences), and
ed159a9fcf2a is an example where the test fails and reports 'no result code from
test'. Hopefully those cases will become even more rare if people don't need to
guess at when a glob is needed for a Windows path.
It's probably unreasonable to submit a single patch that wipes out all of the
(glob) instances that were only used to hide path differences, given the churn
from other contributors. Since their presence isn't harming the tests, these
can be removed through attrition.
We already do this for lines ending in '\n', such that the test only needs to be
run with --interactive and the changes accepted at the end. But that wasn't
working with list-tree.py output for example, and required manual fixup.
Some of the recent work on run-tests.py didn't work on Python 3. This
fixes the regressions.

Essentially, these were acting as a verbose (?) flag, since they weren't being
dropped when required. Foozy has a nice description [1]. Basically, a couple
more places needed to check the features before treating it as optional.
I don't like how test-run-tests.py had to be hacked, but _hghave() can't be made
a static method. The test change was a change while developing `debugssl`,
prior to tightening up the cases where the message is printed, that this fix
would have caught.

Extend the message with the test name and the approximate line number. (The
line number is the one of the command producing the output.)
Finding the line to fix is easier now.
old message:
......
Info, unnecessary glob: at a/b/c (glob)
..
new message:
......
Info, unnecessary glob in test-example.t (after line 9): at a/b/c (glob)
..
The test result is still pass as before.
When the line does not match because of \ instead of / (on windows), append
(glob) in the expected output.
This allows to rename test-bla.t.err to test-bla.t for getting a correct
output. This worked for other failures like missing (esc), but not here.
Output example (only +- lines of diff):
Before:
- path/with/local/sep
+ path\\with\\local/sep
Now:
- path/with/local/sep
+ path/with/local/sep (glob)
