*blib2to3's support was left untouched because: 1) I don't want to touch
parsing machinery, and 2) it'll allow us to provide a more useful error
message if someone does try to format Python 2 code.
* re-implement simple CORS middleware for blackd
* remove aiohttp-cors from setup.py
* Remove aiohttp-cors from Pipfile.lock

The fix for #1688 in #1761 breaks help("modules") introspection and also leads
to unhappy results when inadvertently importing blackd from Python. Basically
the sys.exit(-1) causes the whole Python REPL to exit -- not great to suffice.
Commit history before merge:
* Change sys.exit to Raise.
* Add #2440 to changelog.
* Fix lint error from prettier
* Remove exception chain for more helpful user message.

* 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
- If no aiohttp* deps exist nicely print a helpful message and exit
- There seems to be no nice way to optionally install the entry point, so lets make the entry point nicer
Test:
```
cooper-mbp1:black cooper$ /tmp/tb/bin/pip install .
cooper-mbp1:black cooper$ /tmp/tb/bin/blackd
aiohttp dependency is not installed: No module named 'aiohttp'. Please re-install black with the '[d]' extra install to obtain aiohttp_cors: `pip install black[d]`
cooper-mbp1:black cooper$ /tmp/tb/bin/pip install .[d]
...
Successfully installed aiohttp-3.6.3 aiohttp-cors-0.7.0 black
cooper-mbp1:black cooper$ /tmp/tb/bin/blackd
blackd version 20.8b2.dev31+gdd2f86a.d20201013 listening on localhost port 45484
```
Fixes#1688
- Move black.py to src/black/__init__.py
- Have setuptools_scm make src/_black_version.py and exclude from git
- Move blackd.py to src/blackd/__init__.py
- Move blib2to3/ to src/
- Update `setup.py`
- Update unittests to pass
- Mostly path fixing + resolving
- Update CI
- pre-commit config
- appveyor + travis
Tested on my mac with python 3.7.5 via:
```
python3 -m venv /tmp/tb3
/tmp/tb3/bin/pip install --upgrade setuptools pip coverage pre-commit
/tmp/tb2/bin/pip install ~/repos/black/
cd ~/repos/black/
/tmp/tb2/bin/coverage run tests/test_black.py
/tmp/tb3/bin/pre-commit run -a
/tmp/tb3/bin/black --help
/tmp/tb3/bin/black ~/repos/ptr/ptr.py
```
