bpo-45439: Move _PyObject_VectorcallTstate() to pycore_call.h (GH-28893)
* Move _PyObject_VectorcallTstate() and _PyObject_FastCallTstate() to
  pycore_call.h (internal C API).
* Convert PyObject_CallOneArg(), PyObject_Vectorcall(),
  _PyObject_FastCall() and PyVectorcall_Function() static inline
  functions to regular functions.
* Add _PyVectorcall_FunctionInline() static inline function.
* PyObject_Vectorcall(), _PyObject_FastCall(), and
  PyObject_CallOneArg() now call _PyThreadState_GET() rather
  than PyThreadState_Get().

bpo-45439: Move _PyObject_CallNoArgs() to pycore_call.h (GH-28895)
* Move _PyObject_CallNoArgs() to pycore_call.h (internal C API).
* _ssl, _sqlite and _testcapi extensions now call the public
  PyObject_CallNoArgs() function, rather than _PyObject_CallNoArgs().
* _lsprof extension is now built with Py_BUILD_CORE_MODULE macro
  defined to get access to internal _PyObject_CallNoArgs().

bpo-45439: Rename _PyObject_CallNoArg() to _PyObject_CallNoArgs() (GH-28891)
Fix typo in the private _PyObject_CallNoArg() function name: rename
it to _PyObject_CallNoArgs() to be consistent with the public
function PyObject_CallNoArgs().

Clean up initialization __class_getitem__ with Py_GenericAlias. (GH-28450)
The cast to PyCFunction is redundant. Overuse of redundant casts
can hide actual bugs.

bpo-40137: Add pycore_moduleobject.h internal header (GH-25507)
Add pycore_moduleobject.h internal header file with static inline
functions to access module members:

* _PyModule_GetDict()
* _PyModule_GetDef()
* _PyModule_GetState()

These functions don't check at runtime if their argument has a valid
type and can be inlined even if Python is not built with LTO.

_PyType_GetModuleByDef() uses _PyModule_GetDef().

Replace PyModule_GetState() with _PyModule_GetState() in the
extension modules, considered as performance sensitive:

* _abc
* _functools
* _operator
* _pickle
* _queue
* _random
* _sre
* _struct
* _thread
* _winapi
* array
* posix

The following extensions are now built with the Py_BUILD_CORE_MODULE
macro defined, to be able to use the internal pycore_moduleobject.h
header: _abc, array, _operator, _queue, _sre, _struct.

bpo-42536: GC track recycled tuples (GH-23623)
Several built-in and standard library types now ensure that their internal result tuples are always tracked by the garbage collector:

- collections.OrderedDict.items
- dict.items
- enumerate
- functools.reduce
- itertools.combinations
- itertools.combinations_with_replacement
- itertools.permutations
- itertools.product
- itertools.zip_longest
- zip

Previously, they could have become untracked by a prior garbage collection.

bpo-40071: Fix potential crash in _functoolsmodule.c (GH-19273)
Changes on 7dd549eb08 made _functools compatible with
PEP-489 and we could have multiple modules instances loaded.

But, right now there is no way to make `kwd_mark` global into
a per module instance variable. kwd_mark is used on lru_cache_new
which does not have a reference to a PyModule*, necessary to use
PyModule_GetState.

PEP-573 will solve this problem and will allow us to move the global
state to per-module data and properly clear the state when unloading
a module instance.

This change temporarily disable cleaning of kwd_mark to avoid NULL
pointer dereference if we clear kwd_mark and other module instances
still alive use it.

    old=_PyObject_FastCallDict
