Move the follow functions and type from frameobject.h to pyframe.h,
so the standard <Python.h> provide frame getter functions:
* PyFrame_Check()
* PyFrame_GetBack()
* PyFrame_GetBuiltins()
* PyFrame_GetGenerator()
* PyFrame_GetGlobals()
* PyFrame_GetLasti()
* PyFrame_GetLocals()
* PyFrame_Type
Remove #include "frameobject.h" from many C files. It's no longer
needed.
(cherry picked from commit 27b9894033)
* Fix the compatibility of the Python C API with C++ older than C++11.
* _Py_NULL is only defined as nullptr on C++11 and newer.
(cherry picked from commit 4caf5c2753)
* test_cppext now builds the C++ extension with setuptools.
* Add @test.support.requires_venv_with_pip.
(cherry picked from commit ca0cc9c433)
It combines PyImport_ImportModule() and PyObject_GetAttrString()
and saves 4-6 lines of code on every use.
Add also _PyImport_GetModuleAttr() which takes Python strings as arguments.
(cherry picked from commit 6fd4c8ec77)
Add C++ overloads for _Py_CAST_impl() to handle 0/NULL. This will allow
C++ extensions that pass 0 or NULL to macros using _Py_CAST() to
continue to compile. Without this, you get an error like:
invalid ‘static_cast’ from type ‘int’ to type ‘_object*’
The modern way to use a NULL value in C++ is to use nullptr. However,
we want to not break extensions that do things the old way.

This was added for bpo-40514 (gh-84694) to test out a per-interpreter GIL. However, it has since proven unnecessary to keep the experiment in the repo. (It can be done as a branch in a fork like normal.) So here we are removing:
* the configure option
* the macro
* the code enabled by the macro
Automerge-Triggered-By: GH:ericsnowcurrently
* Add StrongRef class.
* Rename and reformat functions of the _Py_CAST() implementation.

_Py_CAST() cannot be used with a constant type: use _Py_STATIC_CAST()
instead.

Avoid mixing declarations and code in the C API to fix the compiler
warning: "ISO C90 forbids mixed declarations and code"
[-Werror=declaration-after-statement].
(cherry picked from commit 90e7230073)
Use _Py_CAST() and _Py_STATIC_CAST() in macros wrapping static inline
functions of unicodeobject.h.
Change also the kind type from unsigned int to int: same parameter
type than PyUnicode_FromKindAndData().
The limited API version 3.11 no longer casts arguments to expected
types.

Use the PyObject* type for parameters of static inline functions:
* Py_SIZE(): same parameter type than PyObject_Size()
* PyList_GET_SIZE(), PyList_SET_ITEM(): same parameter type than
PyList_Size() and PyList_SetItem()
* PyTuple_GET_SIZE(), PyTuple_SET_ITEM(): same parameter type than
PyTuple_Size() and PyTuple_SetItem().

The limited API version 3.11 no longer casts arguments to expected
types of functions of functions:
* PyList_GET_SIZE(), PyList_SET_ITEM()
* PyTuple_GET_SIZE(), PyTuple_SET_ITEM()

In C++, the _PyObject_EXTRA_INIT macro now uses nullptr, rather than
0, to initialize the _ob_next and _ob_prev members of the PyObject
structure.
Fix test_cppext failure when Python is built with
./configure --with-trace-refs.
Add the -P command line option and the PYTHONSAFEPATH environment
variable to not prepend a potentially unsafe path to sys.path.
* Add sys.flags.safe_path flag.
* Add PyConfig.safe_path member.
* Programs/_bootstrap_python.c uses config.safe_path=0.
* Update subprocess._optim_args_from_interpreter_flags() to handle
the -P command line option.
* Modules/getpath.py sets safe_path to 1 if a "._pth" file is
present.
Convert the following macros to static inline functions:
* PyCFunction_GET_CLASS()
* PyCFunction_GET_FLAGS()
* PyCFunction_GET_FUNCTION()
* PyCFunction_GET_SELF()
Limited C API version 3.11 no longer casts arguments.
Currently, calling Py_EnterRecursiveCall() and
Py_LeaveRecursiveCall() may use a function call or a static inline
function call, depending if the internal pycore_ceval.h header file
is included or not. Use a different name for the static inline
function to ensure that the static inline function is always used in
Python internals for best performance. Similar approach than
PyThreadState_GET() (function call) and _PyThreadState_GET() (static
inline function).
* Rename _Py_EnterRecursiveCall() to _Py_EnterRecursiveCallTstate()
* Rename _Py_LeaveRecursiveCall() to _Py_LeaveRecursiveCallTstate()
* pycore_ceval.h: Rename Py_EnterRecursiveCall() to
_Py_EnterRecursiveCall() and Py_LeaveRecursiveCall() and
_Py_LeaveRecursiveCall()
Fix C++ compiler warnings: "zero as null pointer constant"
(clang -Wzero-as-null-pointer-constant).
* Add the _Py_NULL macro used by static inline functions to use
nullptr in C++.
* Replace NULL with nullptr in _testcppext.cpp.
