gh-102304: Fix Py_INCREF() stable ABI in debug mode (#104763)
When Python is built in debug mode (if the Py_REF_DEBUG macro is
defined), the Py_INCREF() and Py_DECREF() function are now always
implemented as opaque functions to avoid leaking implementation
details like the "_Py_RefTotal" variable or the
_Py_DecRefTotal_DO_NOT_USE_THIS() function.

* Remove _Py_IncRefTotal_DO_NOT_USE_THIS() and
  _Py_DecRefTotal_DO_NOT_USE_THIS() from the stable ABI.
* Remove _Py_NegativeRefcount() from limited C API.

gh-105182: Remove PyEval_AcquireLock() and PyEval_InitThreads() (#105183)
Remove functions in the C API:

* PyEval_AcquireLock()
* PyEval_ReleaseLock()
* PyEval_InitThreads()
* PyEval_ThreadsInitialized()

But keep these functions in the stable ABI.

Mention "make regen-limited-abi" in "make regen-all".

gh-105107: Remove PyCFunction_Call() function (#105181)
* Keep the function in the stable ABI.
* Add unit tests on PyCFunction_Call() since it remains supported in
  the stable ABI.

gh-105145: Remove old functions to config Python init (#105154)
Remove the following old functions to configure the Python
initialization, deprecated in Python 3.11:

* PySys_AddWarnOptionUnicode()
* PySys_AddWarnOption()
* PySys_AddXOption()
* PySys_HasWarnOptions()
* PySys_SetArgvEx()
* PySys_SetArgv()
* PySys_SetPath()
* Py_SetPath()
* Py_SetProgramName()
* Py_SetPythonHome()
* Py_SetStandardStreamEncoding()
* _Py_SetProgramFullPath()

Most of these functions are kept in the stable ABI, except:

* Py_SetStandardStreamEncoding()
* _Py_SetProgramFullPath()

Update Doc/extending/embedding.rst and Doc/extending/extending.rst to
use the new PyConfig API.

_testembed.c:

* check_stdio_details() now sets stdio_encoding and stdio_errors
  of PyConfig.
* Add definitions of functions removed from the API but kept in the
  stable ABI.
* test_init_from_config() and test_init_read_set() now use
  PyConfig_SetString() instead of PyConfig_SetBytesString().

Remove _Py_ClearStandardStreamEncoding() internal function.

gh-105107: Remove PyEval_CallFunction() function (#105108)
Remove 4 functions from the C API, deprecated in Python 3.9:

* PyEval_CallObjectWithKeywords()
* PyEval_CallObject()
* PyEval_CallFunction()
* PyEval_CallMethod()

Keep 3 functions in the stable ABI:

* PyEval_CallObjectWithKeywords()
* PyEval_CallFunction()
* PyEval_CallMethod()

gh-101758: Add _PyState_AddModule() Back for the Stable ABI (gh-101956)
We're adding the function back, only for the stable ABI symbol and not as any form of API. I had removed it yesterday.

This undocumented "private" function was added with the implementation for PEP 3121 (3.0, 2007) for internal use and later moved out of the limited API (3.6, 2016) and then into the internal API (3.9, 2019). I removed it completely yesterday, including from the stable ABI manifest (where it was added because the symbol happened to be exported). It's unlikely that anyone is using _PyState_AddModule(), especially any stable ABI extensions built against 3.2-3.5, but we're playing it safe.

gh-101758: Clean Up Uses of Import State (gh-101919)
This change is almost entirely moving code around and hiding import state behind internal API.  We introduce no changes to behavior, nor to non-internal API.  (Since there was already going to be a lot of churn, I took this as an opportunity to re-organize import.c into topically-grouped sections of code.)  The motivation is to simplify a number of upcoming changes.

Specific changes:

* move existing import-related code to import.c, wherever possible
* add internal API for interacting with import state (both global and per-interpreter)
* use only API outside of import.c (to limit churn there when changing the location, etc.)
* consolidate the import-related state of PyInterpreterState into a single struct field (this changes layout slightly)
* add macros for import state in import.c (to simplify changing the location)
* group code in import.c into sections
*remove _PyState_AddModule()

* Make sure that the current exception is always normalized.

* Remove redundant type and traceback fields for the current exception.

* Add new API functions: PyErr_GetRaisedException, PyErr_SetRaisedException

* Add new API functions: PyException_GetArgs, PyException_SetArgs

gh-98680: Add PyBUF_* constants to the Limited API listing (GH-100018)
``PyBUF_*`` constants are marked as part of Limited API of Python 3.11+.
These were available in 3.11.0 with `Py_LIMITED_API` defined for 3.11,
and are necessary to use the buffer API. Omitting them in `stable_abi.toml`
was a mistake.

gh-47146: Soft-deprecate structmember.h, expose its contents via Python.h (GH-99014)
The ``structmember.h`` header is deprecated, though it continues to be available
and there are no plans to remove it. There are no deprecation warnings. Old code
can stay unchanged (unless the extra include and non-namespaced macros bother
you greatly). Specifically, no uses in CPython are updated -- that would just be
unnecessary churn.
The ``structmember.h`` header is deprecated, though it continues to be
available and there are no plans to remove it.

Its contents are now available just by including ``Python.h``,
with a ``Py`` prefix added if it was missing:

- `PyMemberDef`, `PyMember_GetOne` and`PyMember_SetOne`
- Type macros like `Py_T_INT`, `Py_T_DOUBLE`, etc.
  (previously ``T_INT``, ``T_DOUBLE``, etc.)
- The flags `Py_READONLY` (previously ``READONLY``) and
  `Py_AUDIT_READ` (previously all uppercase)

Several items are not exposed from ``Python.h``:

- `T_OBJECT` (use `Py_T_OBJECT_EX`)
- `T_NONE` (previously undocumented, and pretty quirky)
- The macro ``WRITE_RESTRICTED`` which does nothing.
- The macros ``RESTRICTED`` and ``READ_RESTRICTED``, equivalents of
  `Py_AUDIT_READ`.
- In some configurations, ``<stddef.h>`` is not included from ``Python.h``.
  It should be included manually when using ``offsetof()``.

The deprecated header continues to provide its original
contents under the original names.
Your old code can stay unchanged, unless the extra include and non-namespaced
macros bother you greatly.

There is discussion on the issue to rename `T_PYSSIZET` to `PY_T_SSIZE` or
similar. I chose not to do that -- users will probably copy/paste that with any
spelling, and not renaming it makes migration docs simpler.

Adjust stable ABI internal documentation (GH-96896)
I was perusing this file, and noticed that this part of the documentation is slightly out of date: the `struct` items in this TOML file currently contain `struct_abi_kind` members, which distinguish between the different types of ABI compatibility described in the comment.

I've updated the comment to reflect this.

gh-60074: add new stable API function PyType_FromMetaclass (GH-93012)
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.

gh-85858: Remove PyUnicode_InternImmortal() function (#92579)
Remove the PyUnicode_InternImmortal() function and the
SSTATE_INTERNED_IMMORTAL macro.

The PyUnicode_InternImmortal() function is still exported in the
stable ABI. The function is removed from the API.

PyASCIIObject.state.interned size is now a single bit, rather than 2
bits.

Keep SSTATE_NOT_INTERNED and SSTATE_INTERNED_MORTAL macros for
backward compatibility, but no longer use them internally since the
interned member is now a single bit and so can only have two values
(interned or not interned).

Update stats of _PyUnicode_ClearInterned().
