This patch makes some static to static inline, makes most struct city into
consts, cleans up some style issues and adds some comments. The primary
reason for the patch is to document what functions that change city
contents and which do not.
The aim is to eventually separate out the calculation parts from the
modify-city code, so that the former can be used in AI code without
actually altering any city state.
