00cda79cf5 add io.TextIOWrapper.read in 3.3 (#2248) 
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.

3032fbdff1 make http.client.HTTPResponse concrete in 3.4 (#2244) 
Matches the implementation in https://github.com/python/cpython/blob/3.4/Lib/http/client.py#L308

The ignore works around python/mypy#5027 (commented further up in the 3.5 branch).

Part of #1476.

6b36b1befe Iterator provides a concrete __iter__ in 2.7 (#2245) 
This is already how it works in the Python 3 stub.

`Iterator.__iter__` also exists at runtime: https://github.com/python/cpython/blob/2.7/Lib/_abcoll.py#L73.

7c3edba6ce python2/gettext improvements (#2235) 
* py2: gettext: info()

returns a Dict[str, str]

<https://docs.python.org/2/library/gettext.html#gettext.NullTranslations.info>
> Return the “protected” _info variable.

<https://docs.python.org/2/library/gettext.html#the-gnutranslations-class>
> The entire set of key/value pairs are placed into a dictionary and set
> as the “protected” _info instance variable.

* py2: gettext: charset()

returns an Optional[str]

<https://docs.python.org/2/library/gettext.html#gettext.NullTranslations.charset>
> Return the “protected” _charset variable.

<https://docs.python.org/2/library/gettext.html#the-gnutranslations-class>
> If the key Content-Type is found, then the charset property is used to
> initialize the “protected” _charset instance variable, defaulting to
> None if not found.

* py2: gettext: [set_]output_charset()

allows to set an Optional[str]

<https://docs.python.org/2/library/gettext.html#gettext.NullTranslations.output_charset>
> Return the “protected” _output_charset variable.

<https://docs.python.org/2/library/gettext.html#gettext.NullTranslations.set_output_charset>
> Change the “protected” _output_charset variable, which defines the
> encoding used to return translated messages.

<https://docs.python.org/2/library/gettext.html#gettext.GNUTranslations.lgettext>
> Equivalent to gettext(), but the translation is returned in the
> preferred system encoding, if no other encoding was explicitly set with
> set_output_charset().

* py2: gettext: install(..., names)

allows to set an Optional[str]

<https://docs.python.org/2/library/gettext.html#gettext.NullTranslations.install>
> If the names parameter is given, it must be a sequence containing the
> names of functions you want to install in the builtins namespace in
> addition to _().

* py2: gettext: localdir=None

is Optional[str]

<https://docs.python.org/2/library/gettext.html#gettext.bindtextdomain>
> If localedir is omitted or None, then the current binding for domain
> is returned.

* py2: gettext: languages=None

is Optional[Sequence[str]]

<https://docs.python.org/2/library/gettext.html#gettext.find>
> If languages is not given, then the following environment variables
> are searched: ...

* py2: gettext: codeset=None

is Optional[str]

<https://docs.python.org/2/library/gettext.html#gettext.translation>
> If provided, codeset will change the charset used to encode translated
> strings.

* py2: gettext: translation(class_=None)

is Optional[type]

<https://docs.python.org/2/library/gettext.html#gettext.translation>
> The actual class instantiated is either class_ if provided, otherwise
> GNUTranslations.

* py2: gettext: translation(fallback)

is bool

<https://docs.python.org/2/library/gettext.html#gettext.translation>
> ..., this function raises IOError if fallback is false (which is the
> default), and returns a NullTranslations instance if fallback is true.

* py2: gettext: install(unicode)

is bool

<https://docs.python.org/2/library/gettext.html#gettext.install>
> The unicode flag is passed to the resulting translation object’s
> install() method.

which is already expecting `bool`.

5054465746 Make concurrent.futures stubs identical (#2237) 
Make the Python 2 and 3 concurrent.futures stubs identical so fixes get
applied to both.

For example, #1305 and #2233 fixed the same problem at different times,
as did #1078 and #1911.

By making the stubs identical, we apply the fix from #1711 to Python 2.

Fixes #2234.

451deba4ef memoryview type information inconsistent with runtime behavior (#2230) 
memoryview type information inconsistent with documentation of typing module. 

`memoryview` should be a ByteString like the docs say. 
`memoryview.__init__` does not accept str, and instead of a union it should just accept ByteString. 
`memoryview.__iter__` returns an Iterator[int] not bytes.

4b5a63d10f Fix werkzeug.wrappers.BaseResponse.__init__ (#2232) 
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].

15ad132393 Werkzeug stub fixes (#2229) 
* Fix stub for werkzeug.exceptions.Aborter and abort

* `werkzeug.exceptions.abort` [1] was missing and is thus added here.
  It's also commonly used in Flask as `flask.abort`.
* They both always raise [2], hence the `NoReturn` return type.

[2]: d129d17066/werkzeug/exceptions.py (L708-L713)

* Fix stub for werkzeug.wrappers.AuthorizationMixin

The code [1] uses `@cached_property` [2], which is basically a Python
property, and optionally returns an `Authorization` [3] object.

52c02a2364 Allow Any type to be acceptable for the msg parameter in `logging.{info, warn, error, ...} (#1776) 
The stdlib accepts any value here as long as it is castable to a string:

https://github.com/python/cpython/blob/3.6/Lib/logging/__init__.py#L336
https://github.com/python/cpython/blob/2.7/Lib/logging/__init__.py#L319-L330

Ideally this would use Protocols but I don't see them in use in typeshed yet.

bdb06b5b81 improve codecs stubs (#2114) 
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)
```

d2469c0e89 fix type for itertools.product (#2129) 
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))
