[Freeciv-Dev] (PR#6830) remove map_adjust_x/map_adjust_y

["Jason Short" <jdorje@xxxxxxxxxxxxxxxxxxxxx>]

<URL: http://rt.freeciv.org/Ticket/Display.html?id=6830 >

This clever little patch removes map_adjust_x and map_adjust_y.  They 
are currently unused, have been for a while, and should remain so.

All old callers now use normalize_map_pos, nearest_real_pos, or 
map_distance_vector instead.
