This additionally allows strings, bytearrays and string iterables to be
passed as the `response` argument of `BaseResponse` (and thus also
`Response`).
Strings and bytearrays are explicitly handled in `__init__` [1].
Strings are also featured on the Werkzeug front-page snippet (`'Hello
World!'`) [2].

optparse.Values is like argparse.Namespace and also has a __getattr__() method to return the parsed options.

Started out as progress towards #1476, but I ended up fixing a few more things:
- fixed the signature of _encode_type, which actually returns a pair, not a string
- made some attributes into properties in order to prevent the descriptor protocol from turning them into methods
- found a bug in CPython in the process (python/cpython#6779)
I used the following test file to make sure these classes are now instantiable:
```python
import codecs
import io
from typing import IO
bio = io.BytesIO()
cod = codecs.lookup('utf-8')
codecs.StreamReaderWriter(bio, codecs.StreamReader, codecs.StreamWriter)
codecs.StreamRecoder(bio, cod.encode, cod.decode, codecs.StreamReader, codecs.StreamWriter)
```
Fixes#1850.
The fix was already applied to Python 2, but the typevar-based solution there
leads to "cannot infer value of type variable" in mypy. I used the following
script to check:
```python
from itertools import product
reveal_type(product([1]))
reveal_type(product([1], ['x'], [False], [3.0], [(1,)], [('x',)], [{1}], [{1: 2}], repeat=5))
```
Fixes#1940.
This makes it so that mypy will infer the common base class of these
classes to be Awaitable instead of Iterable. I verified that this
fixes the errors in the script posted by @neilconway.
The annotations, formatarg, formatvarargs, formatvarkw, formatvalue,
formatreturns, and formatannotations arguments to inspect.formatargspec
have default values, but they cannot be None.
This module is going to be used by mypy for the daemon on Windows. To that end I ran stubgen on _winapi, then read through Modules/_winapi.c to add the function types. This seems to have been added in Python 3.1, but I think it is completely fine to just leave it in stdlib/3.
* add inspect.{isasyncgenfunction,isasyncgen} (3.6)
* reorder inspect.CO_* as in Python 3.6 doc
* add inspect.CO_{COROUTINE,ITERABLE_COROUTINE} (3.5)
* add inspect.CO_ASYNC_GENERATOR (3.6)
* use variable annotations
* use version checks
* Parameter.empty is a class attribute
* Signature.empty is a class attribute
The Python 2 version was slightly outdated compared to the Python 3
version.
The Python 2 version of Headers.__delitem__() had an optional argument
_index_operation that also exists in the implementation. But considering
this is internal use only, it was missing from the Python 3 version, and
it created problems with derived classes, I decided not to add it to
the merged stub. See also pallets/werkzeug#1051.
* fix type for TestCase.assertIn
This does essentially `assert member in container`, so we want a `Container`, not an `Iterable`.
This came up in 68e9d426a8..0bbee43d60 (r192525658).
* use any for assertIn
