patch 9.1.0784: there are several problems with python 3.13
Problem: there are several problems with python 3.13
Solution: fix the problems in the python3 interface (Boris Staletic)
This commit does the following things:
1) Since python 3.13.0b1, all statically defined objects are "immortal".
Besides never getting garbage collected, this also affects reference
counting:
- Immportal objects have a reference count of 2^32-1.
- Reference counting is a no-op.
All this is considered implementation details by cpython, so
documentation is next to non-existent.
Relevant CPython source code:
https://github.com/python/cpython/blob/v3.13.0/Include/object.h#L62-L107
https://github.com/python/cpython/blob/v3.13.0/Include/object.h#L389-L391
2) Opt-out of ANSI-painted python stack traces
3) Make python error message severity more consistent
fixes: #15838
closes: #15842
