This checks the bases of of a type created using the FromSpec
API to inherit the bases metaclasses. The metaclass's alloc
function will be called as is done in `tp_new` for classes
created in Python.

* Remove outdated notes from functions that aren't in the Limited API
Nowadays everything that *is* in the Limited API has a note added
automatically.
These notes could mislead people to think that these functions
could never be added to the limited API. Remove them.
* Also remove forgotten note on tp_vectorcall_offset not being finalized
Added a new stable API function ``PyType_FromMetaclass``, which mirrors
the behavior of ``PyType_FromModuleAndSpec`` except that it takes an
additional metaclass argument. This is, e.g., useful for language
binding tools that need to store additional information in the type
object.
Python now always use the ``%zu`` and ``%zd`` printf formats to
format a size_t or Py_ssize_t number. Building Python 3.12 requires a
C11 compiler, so these printf formats are now always supported.
* PyObject_Print() and _PyObject_Dump() now use the printf %zd format
to display an object reference count.
* Update PY_FORMAT_SIZE_T comment.
* Remove outdated notes about the %zd format in PyBytes_FromFormat()
and PyUnicode_FromFormat() documentations.
* configure no longer checks for the %zd format and no longer defines
PY_FORMAT_SIZE_T macro in pyconfig.h.
* pymacconfig.h no longer undefines PY_FORMAT_SIZE_T: macOS 10.4 is
no longer supported. Python 3.12 now requires macOS 10.6 (Snow
Leopard) or newer.
Update documentation of PyUnicode_DecodeFSDefault(),
PyUnicode_DecodeFSDefaultAndSize() and PyUnicode_EncodeFSDefault():
they now use the filesystem encoding and error handler of PyConfig,
Py_FileSystemDefaultEncoding and Py_FileSystemDefaultEncodeErrors
variables are no longer used.
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.
* Remove redundant footnote ref: the footnote has been removed
* Fix footnote ref to match footnote
* Convert footnotes into reST footnotes: will error if missing
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:
* PyByteArray_AS_STRING()
* PyByteArray_GET_SIZE()
* PyBytes_AS_STRING()
* PyBytes_GET_SIZE()
Limited C API version 3.11 no longer casts arguments.
Add _PyBytes_CAST() and _PyByteArray_CAST() macros.
Py_REFCNT(), Py_TYPE(), Py_SIZE() and Py_IS_TYPE() functions argument
type is now "PyObject*", rather than "const PyObject*".
* Replace also "const PyObject*" with "PyObject*" in functions:
* _Py_strhex_impl()
* _Py_strhex_with_sep()
* _Py_strhex_bytes_with_sep()
* Remove _PyObject_CAST_CONST() and _PyVarObject_CAST_CONST() macros.
* Py_IS_TYPE() can now use Py_TYPE() in its implementation.
* Revert "bpo-46850: Move _PyInterpreterState_SetEvalFrameFunc() to internal C API (GH-32054)"
This reverts commit f877b40e3f.
* Revert "bpo-46850: Move _PyEval_EvalFrameDefault() to internal C API (GH-32052)"
This reverts commit b9a5522dd9.
Move the private _PyFrameEvalFunction type, and private
_PyInterpreterState_GetEvalFrameFunc() and
_PyInterpreterState_SetEvalFrameFunc() functions to the internal C
API. The _PyFrameEvalFunction callback function type now uses the
_PyInterpreterFrame type which is part of the internal C API.
Update the _PyFrameEvalFunction documentation.
