I've been working on getting the tree ready to switch ports from python
3.12 to 3.13, this is a good time in our release cycle as there will
probably be some runtime issues in ports using it that need fixing
(various parts of the standard library were removed).

The diff is 16k lines so I won't include it directly, you can get it
here:

https://github.com/openbsd/ports/compare/master...sthen:ports:py313.diff

(not included: revision bumps for the many ports with plist changes).

I think it's ready now, but because site-packages is in a versioned
dir, switching means updating a large set of packages, so I'd want
to commit at the end of h2k25 to avoid causing hassle for people who
will be there.

Any comments/concerns?  Thanks.
