[Freeciv-Dev] (PR#8643) RFC: new file for topology code

["Jason Short" <jdorje@xxxxxxxxxxxxxxxxxxxxx>]

<URL: http://rt.freeciv.org/Ticket/Display.html?id=8643 >

I'd like to create a new file common/topology for the topology code.  We 
have a growing amount of such code, and since a lot of it is inline it 
is cluttering up map.h.

We might consider making all topology functions inline and having _only_ 
common/topology.h.

Thoughts?

If nobody's opposed to the general idea, I'll make a list of what code 
can be moved.

BTW: this should probably be done _after_ common/ is split.
