Build the _multiprocessing.posixshmem extension with the Limited C
API.
* Add <errno.h> include.
* Replace PyUnicode_AsUTF8() with PyUnicode_AsUTF8AndSize().
There were a few things I did in gh-110565 that need to be fixed. I also forgot to add tests in that PR.
(Note that this PR exposes a refleak introduced by gh-110246. I'll take care of that separately.)
* Replace PyStructSequence_SET_ITEM() with
PyStructSequence_SetItem().
* Replace PyTuple_GET_SIZE() with PyTuple_Size().
* Replace PyTuple_GET_ITEM() with PyTuple_GetItem().
Move the following private functions and structures to
pycore_modsupport.h internal C API:
* _PyArg_BadArgument()
* _PyArg_CheckPositional()
* _PyArg_NoKeywords()
* _PyArg_NoPositional()
* _PyArg_ParseStack()
* _PyArg_ParseStackAndKeywords()
* _PyArg_Parser structure
* _PyArg_UnpackKeywords()
* _PyArg_UnpackKeywordsWithVararg()
* _PyArg_UnpackStack()
* _Py_ANY_VARARGS()
Changes:
* Python/getargs.h now includes pycore_modsupport.h to export
functions.
* clinic.py now adds pycore_modsupport.h when one of these functions
is used.
* Add pycore_modsupport.h includes when a C extension uses one of
these functions.
* Define Py_BUILD_CORE_MODULE in C extensions which now include
directly or indirectly (via code generated by Argument Clinic)
pycore_modsupport.h:
* _csv
* _curses_panel
* _dbm
* _gdbm
* _multiprocessing.posixshmem
* _sqlite.row
* _statistics
* grp
* resource
* syslog
* _testcapi: bad_get() no longer uses METH_FASTCALL calling
convention but METH_VARARGS. Replace _PyArg_UnpackStack() with
PyArg_ParseTuple().
* _testcapi: add PYTESTCAPI_NEED_INTERNAL_API macro which is defined
by _testcapi sub-modules which need the internal C API
(pycore_modsupport.h): exceptions.c, float.c, vectorcall.c,
watchers.c.
* Remove Include/cpython/modsupport.h header file.
Include/modsupport.h no longer includes the removed header file.
* Fix mypy clinic.py
* Only add Py_MOD_PER_INTERPRETER_GIL_SUPPORTED to limited C API
version 3.13.
* errno, xxlimited and _ctypes_test extensions now need the limited C
API version 3.13 to get Py_MOD_PER_INTERPRETER_GIL_SUPPORTED. They
now include standard header files explicitly: <errno.h>, <string.h>
and <stdio.h>.
* xxlimited_35: Remove Py_mod_multiple_interpreters slot,
incompatible with limited C API version 3.5.
zipinfo now supports the full range of values in the TZ string
determined by RFC 8536 and detects all invalid formats.
Both Python and C implementations now raise exceptions of the same
type on invalid data.
Now re.error is raised instead of OverflowError or RuntimeError for
too large width of look-behind pattern.
The limit is increased to 2**32-1 (was 2**31-1).
* Use explicit initialiser for m_base
* Add module state stub; establish global state on stack
* Put conversion factors in state struct
* Move PyDateTime_TimeZone_UTC to state
* Move PyDateTime_Epoch to state struct
* Fix ref leaks in and clean up initialisation
Add wrapper for timerfd_create, timerfd_settime, and timerfd_gettime to os module.

* Use `FindFirstFile` Win32 API to fix a bug where `ntpath.realpath()`
breaks out of traversing a series of paths where a (handled)
`ERROR_ACCESS_DENIED` or `ERROR_SHARING_VIOLATION` occurs.
* Update docs to reflect that `ntpath.realpath()` eliminates MS-DOS
style names.
