* Use Tuple field in DecimalTuple
* Remove unnecessary base classes from Decimal
* Decimal.__init__ -> __new__
* Decimal.__ne__ is not defined in Python 3
* Add Decimal.as_integer_ratio()
* Annotate DecimalException.handle()
* Correct types of Decimal method arguments
* Add missing arguments and optional markers to Decimal
* Add missing arguments to Context
* Remove spurious int from Unions with float
* Remove Context.__setattr__()
* Fix return types of Context methods
These type annotations are unnecessary and seem to confuse the type system.
* Remove annotation from PlistFormat enum members
Same rationale as python/typeshed#2314; same adverse effects observed.
Also, mark AST._attributes and _fields as class vars.
`lineno` and `col_offset` were previously defined on a few sub-classes of `AST`, e.g. `expr`, even though https://docs.python.org/3/library/ast.html explicitly states that `AST` has these two attributes. These attributes are only present if they were supplied as arguments to the constructor, but the same is true for the subclasses.
To backport `os.path.commonpath` in mypy I needed to use genericpath. It seems unchanged since 3.4, and the `same*` functions were added in 3.4. (checked via comparing the `__all__`s of the source in 2.7, 3.4, and 3.7.)
* Drop support for Python 3.3
* Merge Python 2 and 3 shutil
* Marked some arguments optional
* Changed callback return type from None to Any for more flexibility
In short, this change makes sure calls like `map(None, a, b)` behave as
expected when using `--no-strict-optional` is enabled.

The previous definitions in `mock` caused many false positives in
internal Dropbox repositories.
One source of problems was `List[Mock]` not being compatible with
`List[SomeClass]`, since `list` is invariant.
`zipfile.ZipFile` is typed to accept `Text` for local and archive file
paths. In Python 3.6, several `ZipFile` methods accept `pathlib.Path`
objects, not just `str` objects. Generalize `ZipFile`'s methods so code
using `pathlib.Path` with `ZipFile` type-checks.
I verified (using my own project) that the following methods work with
os.PurePath at runtime on CPython 3.6:
* zipfile.ZipInfo.__init__
* zipfile.ZipInfo.extractall
* zipfile.ZipInfo.write
This is needed to make TextIOWrapper and a few classes that inherit
from it concrete in 3.3. I am actually not sure whether this method
exists at runtime; there's nothing in
https://docs.python.org/3/library/io.html#io.TextIOWrapper
that suggests it was added in 3.4. In any case, it hardly matters
since 3.3 usage should be very rare now.
