[freeciv-ai] A better AI Eval buildings

[Raahul Kumar <raahul_da_man@xxxxxxxxx>]

This is code ripped out from Ross's corecleanups 13. I've split into smaller
and smaller sections in the hope that someone will actually take an interest.
This 
is pure cleanup.

There was no testing, even just a compile test, because my CVS version does not
currently compile. Not due to this patch, it's an autoconf 2.52 issue.

Ross: Can you run savegames with this patch, and test to see there are in fact
no behaviour changes. I'm 99.5% sure that is the case, but it's nice to have
savegames in hand.

This patch applies cleanly to CVS Mar 5.

Aloha,
RK.
