1dd1b701c9 _typeshed: add SupportsLessThan, SupportsLessThanT (#4711) 
And use it everywhere. Note there seemed to be a discrepancy between
heapq in Python 2 and 3, so I changed that. It should probably be more
widely used within heapq, but leaving that out of scope for this PR.

e61f1783fb add undocumented _heapify_max to heapq stubs (#4708) 
Closes #3926

_heapify_max() existed in Python2 already and hasn't changed in python3 (checked in 3.9)

d6d2249edc builtins: rename _LT (#4579) 
Having an obscure type variable name is causing some pretty inscrutable
errors. For instance:
```
xarray/core/utils.py:466: error: Value of type variable "_LT" of "sorted" cannot be "K"
tornado/simple_httpclient.py:324: error: Value of type variable "_LT" of "min" cannot be "Optional[float]"
```

I think having a more descriptive type variable name here is better for
user experience and helps address the "why" of an error.

276d0428b9 Avoid false positivies from urlparse (Python 2) (#4437) 
PR #3887 changed some `str` types to `Union[str, unicode]`.  The `str`
types were too narrow, but the new types are too general, resulting in
around 80 false positives in a Dropbox internal repository.

I think that it's better to narrow down the types back some to avoid
the false positives, as these are commonly used functions.

Test cases:

```
from urlparse import urlunparse, urlunsplit, urljoin, urlparse, urlsplit

reveal_type(urlunparse(('1', '2', '3', '4', '5', '6'))) # str
reveal_type(urlunparse(['1', '2', '3', '4', '5', '6'])) # str
reveal_type(urlunparse((u'1', '2', '3', '4', '5', '6'))) # unicode
reveal_type(urlunparse([u'1', '2', '3', '4', '5', '6'])) # unicode

reveal_type(urlunsplit(('1', '2', '3', '4', '5'))) # str
reveal_type(urlunsplit(['1', '2', '3', '4', '5'])) # str
reveal_type(urlunsplit((u'1', '2', '3', '4', '5'))) # unicode
reveal_type(urlunsplit([u'1', '2', '3', '4', '5'])) # unicode

reveal_type(urljoin('x', 'y')) # str
reveal_type(urljoin(u'x', 'y')) # unicode
reveal_type(urljoin('x', u'y')) # unicode

reveal_type(urlparse('x').path) # str
reveal_type(urlparse(u'x').path) # str
reveal_type(urlparse(u'x').username) # Optional[str]

reveal_type(urlsplit('x').path) # str
reveal_type(urlsplit(u'x').path) # str
```

83e955b52f Use correct return type annotation for BaseException.with_traceback (#4298) 
The return type of the BaseException.with_traceback() method [1] is not
specific enough. The return type is guaranteed to be of the same type as
‘self’, which is usually a subclass of BaseException.

In fact, .with_traceback() returns ‘self’:

    try:
        raise ValueError
    except Exception as exc:
        assert exc.with_traceback(None) is exc

Fix the annotation to reflect this using the self-type annotation
technique described in PEP484 [2], which is supported by (at least)
mypy [3].

0142a87da8 adjust isort config (#4290) 
Fixes #4288.

- Default imports to THIRD_PARTY, so in effect we merge the FIRST_PARTY and THIRD_PARTY stubs. This means import order is no longer affected by whether typing_extensions is installed locally.
- Treat typing_extensions, _typeshed and some others as standard library modules.

Note that isort master is very different from the latest release; we'll have to do something
different if and when the next isort release comes out.

fb398b1d59 Use the ReadableBuffer type in more places (#4245) 
This is a follow-up on #4232. memoryview, hashlib, and hmac are updated
to use ReadableBuffer type instead of their own home-spun unions of
bytes, bytearray and whatever else each use case used. mmap is being
handled in #4244, and I'll leave BinaryIO for another day (or possibly
another person) because it's going to require some messy code
duplication because the relevant methods are defined in IO[AnyStr].

There's one corner case I'm not quite sure how best to handle: the
documentation for hmac.digest claim that the parmaeters have the same
meanings as in hmac.new, but in CPython the latter has an explicit check
that `key` is bytes or bytearray while the former works with a
memory-view. For now I've matched the documentation.

Also, the documentation for HMAC.update says that `msg` can be any type
supported by hashlib from Python 3.4; but I can't see anything in the
Python 2.7 implementation that would prevent it also taking bytes-like
objects, so I've not tried to treat Python 2 any different to Python 3.

adeda24fce open: introduce concrete return types (#4146) 
* make io classes inherit from typing IO classes

This makes these classes usable if type annotations are given as "IO"
or "TextIO". In the future, we'll then be able to move open() to
return a concrete class instead (#3951).

* open: introduce concrete return types

Fixes #3951.

We use the values of the "mode" and "buffering" arguments to figure out
the concrete type open() will return at runtime. (Compare the CPython
code in https://github.com/python/cpython/blob/master/Modules/_io/_iomodule.c#L231.)
