builtins.warn is a simple builtin that makes evaluation time warnings with the ability to turn them into errors. It's implemented in CppNix and has no meaningful compatibility hazards, so we should port it!

I am going to try to port this. Looks like a good way to get to know the codebase a little better.

The introduction of NIX_ABORT_ON_WARN in the PR seems a bit arbitrary given that it isn't done for any of the other settings. 🤔

Edit: never mind, it makes sense after reading https://github.com/NixOS/nixpkgs/pull/306026 and we should add it, too.

hm… better to wait for you to be done then, I suppose.

I abandoned the previous small refactoring, so 2248 is now the full feature.
