ac5bbd43bc bpo-30248: Convert boolean arguments only once in _json. (#1423) 
Rather than saving the Python object and calling PyObject_IsTrue()
every time when the boolean argument is used, call it only once and
save C boolean value.

76a3e51a40 bpo-30243: Fixed the possibility of a crash in _json. (#1420) 
It was possible to get a core dump by using uninitialized
_json objects. Now __new__ methods create initialized objects.
__init__ methods are removed.

d1302c0154 Issue #28999: Use Py_RETURN_NONE, Py_RETURN_TRUE and Py_RETURN_FALSE wherever 
possible but Coccinelle couldn't find opportunity.

4c38154a43 Don't parenthesis in _PyObject_CallMethodId() format 
Issue #28915: Without parenthesis, _PyObject_CallMethodId() avoids the creation
a temporary tuple, and so is more efficient.

de4ae3d486 Backed out changeset b9c9691c72c5 
Issue #28858: The change b9c9691c72c5 introduced a regression. It seems like
_PyObject_CallArg1() uses more stack memory than
PyObject_CallFunctionObjArgs().

27580c1fb5 Replace PyObject_CallFunctionObjArgs() with fastcall 
* PyObject_CallFunctionObjArgs(func, NULL) => _PyObject_CallNoArg(func)
* PyObject_CallFunctionObjArgs(func, arg, NULL) => _PyObject_CallArg1(func, arg)

PyObject_CallFunctionObjArgs() allocates 40 bytes on the C stack and requires
extra work to "parse" C arguments to build a C array of PyObject*.

_PyObject_CallNoArg() and _PyObject_CallArg1() are simpler and don't allocate
memory on the C stack.

This change is part of the fastcall project. The change on listsort() is
related to the issue #23507.

f024d263b4 Issue #23685: Fix usage of PyMODINIT_FUNC in _json, _scproxy, nis, pyexpat 
_codecs_cn, _codecs_hk, _codecs_iso2022, _codecs_jp, _codecs_kr and _codecs_tw
modules.

pyexpat.c doesn't need to redeclare PyMODINIT_FUNC, it's already declared in
Include/pyport.h.
