Undecided if we should target minimal support to freeciv-3.3 (as a big change coming all in one version), or freeciv-3.2 (would allow backporting freeciv-3.3 patches to freeciv-3.2 without changing any nullptr uses)
Well, I wanted to test things with gcc-13 already, and S3_2 has not yet been branched -> this change for current master is for 3.2.
'nullptr' might be the most viable new C23 concept for us to adopt quickly, as it should be easy to do with a fallback in older systems. We already have been using C++ nullptr for a long time, with similar arrangements.
