[Freeciv-Dev] Re: list cleaning

["Per I. Mathisen" <per@xxxxxxxxxxx>]

I want to move ahead on this one. I think my solution is the best one and
I am willing to code it (what remains to be done).

A genlist_destroy has a low code impact, has no speed impact and I can add
a test on quit that does a quality assurance check that we have no missing
genlist_destroy calls in the codebase.

We can have a bool per list which is set to TRUE for lists that have
changed, and are set to FALSE when they are pruned. This way we do no
tests for lists that are not changed.

We do pruning once per turn. That is more than good enough.
