Remove Python 2 support (#2740)
*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.

Reorganize changelog (#2669)
I believe it would be useful to split up the long list of changes a bit more.

Specific changes:
- Removed the entry for new flake8 plugins; this is purely internal and not of interest to users
- Put regex in the packaging section
- New section for Jupyter Notebook
- New section for Python 3.10, mostly match/case stuff

Remove regex dependency (GH-2663)
We were no longer using it since GH-2644 and GH-2654. This should hopefully
make using Black easier to use as there's one less compiled dependency.
The core team also doesn't have to deal with the surprisingly frequent fires
the regex packaging setup goes through.

Treat functions/classes in blocks as if they're nested (GH-2472)
* Treat functions/classes in blocks as if they're nested

One curveball is that we still want two preceding newlines before blocks
that are probably logically disconnected. In other words:

    if condition:

        def foo():
            return "hi"
                             # <- aside: this is the goal of this commit
    else:

        def foo():
            return "cya"
                             # <- the two newlines spacing here should stay
                             #    since this probably isn't related
    with open("db.json", encoding="utf-8") as f:
        data = f.read()

Unfortunately that means we have to special case specific clause types
instead of just being able to just for a colon leaf. The hack used here
is to check whether we're adding preceding newlines for a standalone or
dependent clause. "Standalone" being a clause that doesn't need another
clause to be valid (eg. if) and vice versa.

Reduce usage of regex (#2644)
This removes all but one usage of the `regex` dependency. Tricky bits included:
- A bug in test_black.py where we were incorrectly using a character range. Fix also submitted separately in #2643.
- `tokenize.py` was the original use case for regex (#1047). The important bit is that we rely on `\w` to match anything valid in an identifier, and `re` fails to match a few characters as part of identifiers. My solution is to instead match all characters *except* those we know to mean something else in Python: whitespace and ASCII punctuation. This will make Black able to parse some invalid Python programs, like those that contain non-ASCII punctuation in the place of an identifier, but that seems fine to me.
- One import of `regex` remains, in `trans.py`. We use a recursive regex to parse f-strings, and only `regex` supports that. I haven't thought of a better fix there (except maybe writing a manual parser), so I'm leaving that for now.

My goal is to remove the `regex` dependency to reduce the risk of breakage due to dependencies and make life easier for users on platforms without wheels.

Return NothingChanged if non-Python cell magic is detected, to avoid tokenize error (#2630)
Fixes https://github.com/psf/black/issues/2627 , a non-Python cell magic such as `%%writeline` can legitimately contain "incorrect" indentation, however this causes `tokenize-rt` to return an error. To avoid this, `validate_cell` should early detect cell magics (just like it detects `TransformerManager` transformations).

Test added too, in the shape of a "badly indented" `%%writefile` within `test_non_python_magics`.

Improve Python 2 only syntax detection (GH-2592)
* Improve Python 2 only syntax detection

First of all this fixes a mistake I made in Python 2 deprecation PR
using token.* to check for print/exec statements. Turns out that
for nodes with a type value higher than 256 its numeric type isn't
guaranteed to be constant. Using syms.* instead fixes this.

Also add support for the following cases:

    print "hello, world!"

    exec "print('hello, world!')"

    def set_position((x, y), value):
        pass

    try:
        pass
    except Exception, err:
        pass

    raise RuntimeError, "I feel like crashing today :p"

    `wow_these_really_did_exist`

    10L

* Add octal support, more test cases, and fixup long ints

install build-essential to compile dependencies and use multi-stage build (#2582)
- Install build-essential to avoid build issues like #2568 when dependencies don't have prebuilt wheels available
- Use multi-stage build instead of trying to purge packages and cache from the image
  Copying `/root/.local/` installs only black's built Python dependencies (< 20 MB).
  So the image is barely larger than python:3-slim base image

support completely.

Pin regex in docker to 2021.10.8 (GH-2579)
* Pin regex in docker to 2021.10.8
- This is due to 2021.10.8 having arm wheels and newer versions not

I will go see if I can help restore arm build @ https://bitbucket.org/mrabarnett/mrab-regex/issues/399/missing-wheel-for-macosx-and-the-new-m1 soon.

Test: Build on my M1 mac: `docker build -t cooperlees/black .`

* Add in that the pin is only for docker
