[primer] Enable everything (#2288)
See if we pass all our repos with experimental string processing enabled.
Django probably needed:
- Ignores >= 3.8 only

We could support PEP440 version specifiers, but that would introduce the packaging module as a dependency that I'd like to avoid ... Or I could implement a poor persons version or vendor

Commit history before merge:
 * [primer] Enable everything
 * Add exclude extend to django CLI args for primer
 * Change default timeout to from 5 to 10 mins for a primer project
 * Skip string normalization for Django
 * Limit Django to >= 3.8 due to := operator

Add option to require a specific version to be running (#2300)
Closes #1246: This PR adds a new option (and automatically a toml entry, hooray for existing configuration management 🎉) to require a specific version of Black to be running.

For example: `black --required-version 20.8b -c "format = 'this'"`

Execution fails straight away if it doesn't match `__version__`.

Correct max string length calculation when there are string operators (#2292)
PR #2286 did not fix the edge-cases (e.g. when the string is just long
enough to cause a line to be 89 characters long). This PR corrects that

Add optional uvloop import (#2258)
* Add optional uvloop import

- If we find `uvloop` in the env for black, blackd or black-primer lets try and use it
- Add a uvloop extra install

Fixes #2257

Test:
- Add ci job to install black[uvloop] and run a primer run with uvloop
  - Only with latest python (3.9)
  - Will be handy to compare runtimes as a very unoffical benchmark

* Remove tox install

* Add to CHANGES/news

Removed adding a space into empty docstrings. (#2249)
Resolves #2168 by disabling the insertion of a " " when the docstring is entirely empty.

Note that this PR is focussed only on the case of empty docstrings. In particular this does not make any changes to the behaviour that a " " is inserted if a non-empty docstring begins with the quoting character. That is, black still prefers:

    """ "something" """

to:

    """"something" """

and that:

    """"Something""""

is not a legal docstring.

Solved Problem with Non-ASCII .gitignore Files (#2229)
* Solved Problem with non-alphabetical .gitignore files

When .gitignore file in the user's project directory contained non-alphabetical
characters(Japanese, Korean, Chinese, etc), Nothing works and printed this
weird message in the console('cp949' is the encoding for Korean characters
in this case). It even blocks VSCode's formatting from working. This commit
solves the problem.

Fix: black only respects the root gitignore. (#2225)
Commit history before merge:

Black now respects .gitignore files in all levels, not only root/.gitignore file
(apply .gitignore rules like git does).

* Fix: typo
* Fix: respect .gitignore files in all levels.
* Add: CHANGELOG note.
* Fix: TypeError: unsupported operand type(s) for +: 'NoneType' and 'PathSpec'
* Update docs.
* Fix: no parent .gitignore
* Add a comment since the if expression is a bit hard to understand
* Update tests - conver no parent .gitignore case.
* Use main's Pipfile.lock instead

  The original changes in Pipfile.lock are whitespace only. The changes
  turned the JSON's file indentation from 4 to 2. Effectively this
  happened: `json.dumps(json.loads(old_pipfile_lock), indent=2) + "\n"`.

  Just using main's Pipfile.lock instead of undoing the changes because
  1) I don't know how to do that easily and quickly, and 2) there's a
  merge conflict.

Add lower bound for aiohttp-cors + fix primer (#2231)
It appears sqlalchemy has recently reformatted their project with
Black 21.5b1.

Most of our dependencies have a lower bound and creating a test
environment with the oldest acceptable dependencies runs the full
Black test suite just fine. The only exception to this is aiohttp-cors.
It's unbounded and the oldest version 0.1.0 until 0.4.0 breaks the
test suite in such an old environment.

Failure with 0.1.0:

```
tests/test_blackd.py:10: in <module>
    import blackd
testenv/lib/python3.8/site-packages/blackd/__init__.py:12: in <module>
    import aiohttp_cors
testenv/lib/python3.8/site-packages/aiohttp_cors/__init__.py:29: in <module>
    from .urldispatcher_router_adapter import UrlDistatcherRouterAdapter
testenv/lib/python3.8/site-packages/aiohttp_cors/urldispatcher_router_adapter.py:27: in <module>
    class UrlDistatcherRouterAdapter(RouterAdapter):
testenv/lib/python3.8/site-packages/aiohttp_cors/urldispatcher_router_adapter.py:32: in UrlDistatcherRouterAdapter
    def route_methods(self, route: web.Route):
E   AttributeError: module 'aiohttp.web' has no attribute 'Route'
```

For 0.2.0:

```
tests/test_blackd.py:10: in <module>
    import blackd
testenv/lib/python3.8/site-packages/blackd/__init__.py:12: in <module>
    import aiohttp_cors
testenv/lib/python3.8/site-packages/aiohttp_cors/__init__.py:27: in <module>
    from .cors_config import CorsConfig
testenv/lib/python3.8/site-packages/aiohttp_cors/cors_config.py:24: in <module>
    from .urldispatcher_router_adapter import UrlDistatcherRouterAdapter
testenv/lib/python3.8/site-packages/aiohttp_cors/urldispatcher_router_adapter.py:27: in <module>
    class UrlDistatcherRouterAdapter(AbstractRouterAdapter):
testenv/lib/python3.8/site-packages/aiohttp_cors/urldispatcher_router_adapter.py:32: in UrlDistatcherRouterAdapter
    def route_methods(self, route: web.Route):
E   AttributeError: module 'aiohttp.web' has no attribute 'Route'
```

For 0.3.0:

```
ERROR: Cannot install aiohttp-cors==0.3.0 and aiohttp==3.6.0 because these package versions have conflicting dependencies.

The conflict is caused by:
    The user requested aiohttp==3.6.0
    aiohttp-cors 0.3.0 depends on aiohttp<=0.20.2 and >=0.18.0

To fix this you could try to:
1. loosen the range of package versions you've specified
2. remove package versions to allow pip attempt to solve the dependency conflict

Do not use gitignore if explicitly passing excludes (#2170)
Closes #2164.

Changes behavior of how .gitignore is handled. With this change, the rules in .gitignore are only used as a fallback if no exclusion rule is explicitly passed on the command line or in pyproject.toml. Previously they were used regardless if explicit exclusion rules were specified, preventing any overriding of .gitignore rules.

Those that depend only on .gitignore for their exclusion rules will not be affected. Those that use both .gitignore and exclude will find that exclude will act more like actually specifying exclude and not just another extra-excludes. If the previous behavior was desired, they should move their rules from exclude to extra-excludes.

Don't strip parens in assert / return with assign expr (#2143)
Black would previously strip the parenthesis away from statements like this these ones:

    assert (spam := 12 + 1)
    return (cheese := 1 - 12)

Which happens to be invalid code. Now before making the parenthesis invisible, Black
checks if the assignment expression's parent is an assert stamtment, aborting if True.

Raise, yield, and await are already handled fine.

I added a bunch of test cases from the PEP defining asssignment expressions (PEP 572).

Work around stability errors due to optional trailing commas (#2126)
Optional trailing commas put by Black become magic trailing commas on another
pass of the tool.  Since they are influencing formatting around optional
parentheses, on rare occasions the tool changes its mind in terms of putting
parentheses or not.

Ideally this would never be the case but sadly the decision to put optional
parentheses or not (which looks at pre-existing "magic" trailing commas) is
happening around the same time as the decision to put an optional trailing
comma.  Untangling the two proved to be impractically difficult.

This shameful workaround uses the fact that the formatting instability
introduced by magic trailing commas is deterministic: if the optional trailing
comma becoming a pre-existing "magic" trailing comma changes formatting, the
second pass becomes stable since there is no variable factor anymore on pass 3,
4, and so on.

For most files, this will introduce no performance penalty since `--safe` is
already re-formatting everything twice to ensure formatting stability.  We're
using this result and if all's good, the behavior is equivalent.  If there is
a difference, we treat the second result as the binding one, and check its
sanity again.
