[Freeciv-Dev] (PR#6721) First Goal

["Marcelo Burda" <mburda@xxxxxxxxx>]

<URL: http://rt.freeciv.org/Ticket/Display.html?id=6721 >

this patch speed up 0.7% the original game and make it posible to add 
new topologies with a zero speed down in server for the old ones.

some clean up is waiting, if a make it now  my quincuncial patch is to 
difficult to port,best if we make a clean up when extending.

this patch add, the size and ratio variables and the auto 
init_topologies (for classic, flat, and torus)

Uranus is no included, if you see the list of topologies of my patch 
tere is a great number and uranus is a classical topologie rotated 90.

this way normalize_map_pos and map_vector are faster but call are 
slower, not extend this idea to all topological sub programs, test it 
befor.

this patch can be included fast!
