Log message:
lang/python and a number of python packages: re-do atomic64.mk issue.

Evidently, python 3.13 brought in the need to support 64-bit atomics.
This means that python extension packages built with C needs to
use mk/atomic64.mk to make -latomic available on the required 32-bit
ports.  Sadly, there is no reliable way to detect in the .mk files
whether the package is using C (or C++), so this change adds an
unconditional include of mk/atomic64.mk when the python version is
equal to or larger than 3.13 for packages using egg.mk or wheel.mk.

This undoes the individual package Makefile inclusions of mk/atomic64.mk
that I've added over the last few days.

devel/py-cffi: use atomic64.mk to fix build with python 3.13 on macppc.

py-cffi: updated to 1.17.1

v1.17.1

* Fix failing ``distutils.msvc9compiler`` imports under Windows
* ``ffibuilder.emit_python_code()`` and ``ffibuiler.emit_c_code()`` accept \ 
file-like objects
* ``ffiplatform`` calls are bypassed by ``ffibuilder.emit_python_code()`` and \ 
``ffibuilder.emit_c_code()``

py-cffi: convert to wheel.mk

Does not support Python 2 any longer.

Bump PKGREVISION.

py-cffi: fix for Python 2

Log message:
py-cffi: updated to 1.16.0

v1.16.0

* Add support for Python 3.12. With the removal of ``distutils`` from Python \ 
3.12, projects
  using CFFI features that depend on ``distutils`` at runtime must add a \ 
dependency on
  ``setuptools`` to function under Python 3.12+. CFFI does not declare a runtime \ 
``setuptools``
  requirement to avoid an unnecessary dependency for projects that do not require it.
* Drop support for end-of-life Python versions (2.7, 3.6, 3.7).
* Add support for PEP517 builds; ``setuptools`` is now a required build dependency.
* Declare ``python_requires`` metadata for Python 3.8+. This allows unsupported \ 
Pythons
  to continue using previously released sdists and wheels.
* Move project source under ``src/``; a more standard layout that also enables \ 
CI to more easily
  catch packaging errors.

py-cffi: updated to 1.15.1

v1.15.1
=======

* If you call `ffi.embedding_api()` but don't write any `extern "Python"`
  function there, then the resulting C code would fail an assert.  Fixed.

* Updated Windows/arm64 embedded libffi static lib to v3.4.2, and scripted
  to ease future updates (thanks Niyas Sait!)

They now have a tool dependency on py-setuptools instead of a DEPENDS
