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.

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.
