The _xxsubinterpreters module was meant to only use public API.  Some internal C-API usage snuck in over the last few years (e.g. gh-28969).  This fixes that.

Also includes a reference shell script to implements what is documented.

Since Python 3.12, PyUnicode_READY() does nothing and always
returns 0.

Since Python 3.12, PyUnicode_READY() does nothing and always
returns 0.

Argument Clinic now also checks for .cpp files (PC/_wmimodule.cpp).

When I added the relevant condition to type_ready_set_bases() in gh-103912, I had missed that the function also sets tp_base and ob_type (if necessary).  That led to problems for third-party static types.

We fix that here, by making those extra operations distinct and by adjusting the condition to be more specific.

This avoids the problematic race in drop_gil() by skipping the FORCE_SWITCHING code there for finalizing threads.

(The idea for this approach came out of discussions with @markshannon.)

Upgrade builds to OpenSSL 1.1.1u.

This OpenSSL version addresses a pile if less-urgent CVEs since 1.1.1t.

The Mac/BuildScript/build-installer.py was already updated.

Also updates _ssl_data_111.h from OpenSSL 1.1.1u, _ssl_data_300.h from 3.0.9, and adds a new _ssl_data_31.h file from 3.1.1 along with the ssl.c code to use it.

Manual edits to the _ssl_data_300.h file prevent it from removing any existing definitions in case those exist in some peoples builds and were important (avoiding regressions during backporting).

backports of this prior to 3.12 will not include the openssl 3.1 header.

Deprecate old Python initialization functions:

* PySys_ResetWarnOptions()
* Py_GetExecPrefix()
* Py_GetPath()
* Py_GetPrefix()
* Py_GetProgramFullPath()
* Py_GetProgramName()
* Py_GetPythonHome()

_tkinter.c uses sys.executable instead of Py_GetProgramName()
and uses sys.prefix instead of Py_GetPrefix().

)

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".

Quoting autoconf (v2.71):

    All current systems provide time.h; it need not be checked for.
    Not all systems provide sys/time.h, but those that do, all allow
    you to include it and time.h simultaneously.

* Keep the function in the stable ABI.
* Add unit tests on PyCFunction_Call() since it remains supported in
  the stable ABI.

Update Lib/test/clinic.test manually for updated Py_UNICODE
converter: it now uses wchar_t type rather than Py_UNICODE.

#105178)

* refcounts.dat:

  * Remove Py_UNICODE functions.
  * Replace Py_UNICODE argument type with wchar_t.

* _PyUnicode_ToLowercase(), _PyUnicode_ToUppercase(),
  _PyUnicode_ToTitlecase() are no longer deprecated in comments.
  It's no longer needed since they now use Py_UCS4 type, rather than
  the deprecated Py_UNICODE type.
* gdb: Remove unused char_width() method.

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.

Deprecate the old Py_UNICODE and PY_UNICODE_TYPE types in the C API:
use wchar_t instead.

Replace Py_UNICODE with wchar_t in multiple C files.
