bpo-40170: Remove PyIndex_Check() macro (GH-19428)
Always declare PyIndex_Check() as an opaque function to hide
implementation details: remove PyIndex_Check() macro. The macro
accessed directly the PyTypeObject.tp_as_number member.

bpo-40170: Add _PyIndex_Check() internal function (GH-19426)
Add _PyIndex_Check() function to the internal C API: fast inlined
verson of PyIndex_Check().

Add Include/internal/pycore_abstract.h header file.

Replace PyIndex_Check() with _PyIndex_Check() in C files of Objects
and Python subdirectories.

bpo-40170: PyType_HasFeature() now always calls PyType_GetFlags() (GH-19378)
PyType_HasFeature() now always calls PyType_GetFlags() to hide
implementation details. Previously, it accessed directly the
PyTypeObject.tp_flags member when the limited C API was not used.

Add fast inlined version _PyType_HasFeature() and _PyType_IS_GC()
for object.c and typeobject.c.

bpo-40170: Convert PyObject_CheckBuffer() macro to a function (GH-19376)

bpo-40170: PyObject_NEW() becomes an alias to PyObject_New() (GH-19379)
The PyObject_NEW() macro becomes an alias to the PyObject_New()
macro, and the PyObject_NEW_VAR() macro becomes an alias to the
PyObject_NewVar() macro, to hide implementation details. They no
longer access directly the PyTypeObject.tp_basicsize member.

Exclude _PyObject_SIZE() and _PyObject_VAR_SIZE() macros from
the limited C API.

Replace PyObject_NEW() with PyObject_New() and replace
PyObject_NEW_VAR() with PyObject_NewVar().

bpo-39481: Implementation for PEP 585 (#18239)
This implements things like `list[int]`,
which returns an object of type `types.GenericAlias`.
This object mostly acts as a proxy for `list`,
but has attributes `__origin__` and `__args__`
that allow recovering the parts (with values `list` and `(int,)`.

There is also an approximate notion of type variables;
e.g. `list[T]` has a `__parameters__` attribute equal to `(T,)`.
Type variables are objects of type `typing.TypeVar`.

bpo-37388: Don't check encoding/errors during finalization (GH-19409)
str.encode() and str.decode() no longer check the encoding and errors
in development mode or in debug mode during Python finalization. The
codecs machinery can no longer work on very late calls to
str.encode() and str.decode().

This change should help to call _PyObject_Dump() to debug during late
Python finalization.

bpo-40170: PyObject_GET_WEAKREFS_LISTPTR() becomes a function (GH-19377)
Convert the PyObject_GET_WEAKREFS_LISTPTR() macro to a function to
hide implementation details: the macro accessed directly to the
PyTypeObject.tp_weaklistoffset member.

Add _PyObject_GET_WEAKREFS_LISTPTR() static inline function to the
internal C API.

bpo-39824: module_traverse() don't call m_traverse if md_state=NULL (GH-18738)
Extension modules: m_traverse, m_clear and m_free functions of
PyModuleDef are no longer called if the module state was requested
but is not allocated yet. This is the case immediately after the
module is created and before the module is executed (Py_mod_exec
function). More precisely, these functions are not called if m_size is
greater than 0 and the module state (as returned by
PyModule_GetState()) is NULL.

Extension modules without module state (m_size <= 0) are not affected.

The Py_FatalError() function is replaced with a macro which logs
automatically the name of the current function, unless the

Changes:

* Add _Py_FatalErrorFunc() function.
* Remove the function name from the message of Py_FatalError() calls
  which included the function name.
* Update tests.
