The hard part was making all the tests pass; there are some subtle issues here, because apparently the future import wasn't tested very thoroughly in previous Python versions.
For example, `inspect.signature()` returned type objects normally (except for forward references), but strings with the future import. We changed it to try and return type objects by calling `typing.get_type_hints()`, but fall back on returning strings if that function fails (which it may do if there are future references in the annotations that require passing in a specific namespace to resolve).
* Use ast module to find class definition
* Add NEWS entry
* Fix class with multiple children and move decorator code to the method
* Fix PR comments
1. Use node.decorator_list to select decorators
2. Remove unwanted variables in ClassVisitor
3. Simplify stack management as per review
* Add test for nested functions and async calls
* Fix pydoc test since comments are returned now correctly
* Set event loop policy as None to fix environment related change
* Refactor visit_AsyncFunctionDef and tests
* Refactor to use local variables and fix tests
* Add patch attribution
* Use self.addCleanup for asyncio
* Rename ClassVisitor to ClassFinder and fix asyncio cleanup
* Return first class inside conditional in case of multiple definitions. Remove decorator for class source.
* Add docstring to make the test correct
* Modify NEWS entry regarding decorators
* Return decorators too for bpo-15856
* Move ast and the class source code to top. Use proper Exception.
`list(sys.modules.items())` was apparently not immune to "dictionary
changed size during iteration" errors.
Tested internally using an integration test that has run into this a couple of times in the past two years. With this patch applied, the test is no longer flaky.

Specifically in the case of a class that does not override its
constructor signature inherited from object.
These are Buck Evan @bukzor's changes cherrypicked from GH-9344.
Currently, inspect.getfile(str) will report nonsense:
```pytb
>>> inspect.getfile(str)
TypeError: <module 'builtins' (built-in)> is a built-in class
```
This fixes that

This is consistent with the rest of the `warnings.warn` usage in the
inspect.py module and aids identifying code that needs to be fixed.

This commit contains the implementation of PEP570: Python positional-only parameters.
* Update Grammar/Grammar with new typedarglist and varargslist
* Regenerate grammar files
* Update and regenerate AST related files
* Update code object
* Update marshal.c
* Update compiler and symtable
* Regenerate importlib files
* Update callable objects
* Implement positional-only args logic in ceval.c
* Regenerate frozen data
* Update standard library to account for positional-only args
* Add test file for positional-only args
* Update other test files to account for positional-only args
* Add News entry
* Update inspect module and related tests
inspect.isfunction() processes both inspect.isfunction(func) and
inspect.isfunction(partial(func, arg)) correctly but some other functions in the
inspect module (iscoroutinefunction, isgeneratorfunction and isasyncgenfunction)
lack this functionality. This commits adds a new check in the mentioned functions
in the inspect module so they can work correctly with arbitrarily nested partial
functions.
* bpo-32991: Add test capturing expectation.
DocTestFinder.find should return an empty list for doctests in a namespace package.
* bpo-32991: Restore expectation that inspect.getfile on a namespace package raises TypeError.

Some objects (like test mocks) auto-generate new objects on
attribute access, which can lead to an infinite loop in
inspect.unwrap().
Ensuring references are retained to otherwise temporary objects
and capping the size of the memo dict turns this case into a
conventional exception instead.
At the time when an abstract base class' __init_subclass__ runs,
ABCMeta.__new__ has not yet finished running, so in the presence of
__init_subclass__, inspect.isabstract() can no longer depend only on
TPFLAGS_IS_ABSTRACT.
