Subject: [PATCH] siplib: fix build with python >= 3.11

With python 3.11, the PyFrameObject structure members have been
removed from the public C API:

https://docs.python.org/3.11/whatsnew/3.11.html#whatsnew311-c-api-porting
https://docs.python.org/3.11/whatsnew/3.11.html#pyframeobject-3-11-hiding

This patch migrates to the opaque PyFrameObject.

Upstream: Not Applicable, SIP 4.x is no longer maintained
