Make sure sys._base_executable is sane in Vim plugin (#1380)
The `venv` module relies on `sys._base_executable` to determine the
Python executable to run, but with recent versions of Vim, this is set
to the `vim` executable. A possible workaround is to just override it,
since the `black` plugin already overrides `sys.executable` (possibly
for similar reasons?) anyway.

Re-indent the contents of docstrings (#1053)
* Re-indent the contents of docstrings when indentation changes
Keeping the contents of docstrings completely unchanged when
re-indenting (from 2-space intents to 4, for example) can cause
incorrect docstring indentation:
```
class MyClass:
"""Multiline
class docstring
"""
def method(self):
"""Multiline
method docstring
"""
pass
```
...becomes:
```
class MyClass:
"""Multiline
class docstring
"""
This uses the PEP 257 algorithm for determining docstring indentation,
and adjusts the contents of docstrings to match their new indentation
after `black` is applied.
A small normalization is necessary to `assert_equivalent` because the
trees are technically no longer precisely equivalent -- some constant
strings have changed. When comparing two ASTs, whitespace after
newlines within constant strings is thus folded into a single space.

* Extract the inner `_v` method to decrease complexity
This reduces the cyclomatic complexity to a level that makes flake8 happy.

Improve String Handling (#1132)
This pull request's main intention is to wraps long strings (as requested by #182); however, it also provides better string handling in general and, in doing so, closes the following issues:
Change exit code to 2 when config file doesn't exist (#1361)
Fixes #1360, where an invalid config file causes a return/exit code of 1. This
change means this case is caught earlier, treated like any other bad
parameters, and results in an exit code of 2.
`split("\n")` includes a final empty element `""` if the final line
ends with `\n` (as it should for POSIX-compliant text files), which
then became an extra `"\n"`.
`splitlines()` solves that, but there's a caveat, as it will split
on other types of line breaks too (like `\r`), which may not be
desired.

Notify users of missing Python lazily (#1210)
Currently this message shows up with no context prior to the start of
Vim. By changing this to a lazy message, the user will only be notified
of a problem with the Black plugin when they are attempting to use the
Black plugin.
Fix unstable formatting with some `# type: ignore`s (#1113)
`type: ignore` shouldn't block collapsing a line, since it will still
apply fine to the merged line. This prevents an issue where a reformat
causes it to shift lines and then be merged on a subsequent pass.
There is a downside to this, which is that it can cause a `type:
ignore` to apply to more code than was originally intended. There
might be a way to apply this in a more limited situation, but I'm not
sure what it is.
* Make most of blib2to3 directly typed and mypyc-compatible
This used a combination of retype and pytype's merge-pyi to do the
initial merges of the stubs, which then required manual tweaking to
make actually typecheck and work with mypyc.

* Make black able to compile and run with mypyc
The changes made fall into a couple categories:
* Fixing actual type mistakes that slip through the cracks
* Working around a couple mypy bugs (the most annoying of which being
that we need to add type annotations in a number of places where
variables are initialized to None)

Fix fmt on/off when multiple exist in leaf prefix (#1086)
The old behavior would detect the existence of a `# fmt: on` in a leaf
node's comment prefix and immediately mark the node as formatting-on,
even if a subsequent `# fmt: off` in the same comment prefix would turn
it back off. This change modifies that logic to track the state through
the entire prefix and take the final state.
Note that this does not fully solve on/off behavior, since any _comment_
lines between the off/on are still formatted. We may need to add
virtual leaf nodes to truly solve that. I will leave that for a separate
commit/PR.

s/_version.py/_black_version.py/ (#1082)
Some users are installing Black as a dependency in their project. Having
a _version.py in site-packages is asking for a conflict sooner or later.
Ideally we shouldn't require a separate version file at all, that's an
additional import we need to make. But I'll leave that bikeshedding for
a different time.

Do not load incompatible cache (#875) (#1034)
A black cache created in Python 3.8 throws an unhandled
ValueError in earlier versions. This is because 3.6 does
not recognize the pickle protocol used as default in 3.8.
Accordingly, this commit:
- Fixes read_cache to return an empty cache instead.
- Changes the pickle protocol to 4 as the highest protocol
fully supported by black's supported Python versions.

Back out #850 (#1079)
Fixes #1042 (and probably #1044 which looks like the same thing).
The issue with the "obviously unnecessary" parentheses that #850 removed is that sometimes they're necessary to help Black fit something in one line. I didn't see an obvious solution that still removes the parens #850 was intended to remove, so let's back out this change for now in the interest of unblocking a release.
This PR also adds a test adapted from the failing example in #1042, so that if we try to reapply the #850 change we don't break the same case again.
