Make server check game state file sizes on startup

Browse source 
Certain tables have a fixed size depending on configuration: EF_SECTOR
has WORLD_SZ() elements, EF_NATION, EF_MAP and EF_BMAP have MAXNOC
elements, and EF_REALM has MAXNOC * MAXNOR elements.  Bad things
happen if the files backing them are shorter.

Pass expected size to ef_open(), and make it fail when the actual size
differs.
