/*
* What this function does depends on the value of the 'state' argument:
* SPHERE_TRACKING:
* The sphere of influence for the race for 'which_ship' will be shown
* on the starmap in the future.
* The value returned is 'which_ship', unless the type of ship is only
* available in SuperMelee, in which case 0 is returned.
* SPHERE_KNOWN:
* The size of the fleet of the race of 'which_ship' when the starmap was
* last checked is returned.
* ESCORT_WORTH:
* The total value of all the ships escorting the SIS is returned.
* 'which_ship' is ignored.
* ESCORTING_FLAGSHIP:
* Test if a ship of type 'which_ship' is among the escorts of the SIS
* 0 is returned if false, 1 if true.
* FEASIBILITY_STUDY:
* Test if the SIS can have an escort of type 'which_ship'.
* 0 is returned if 'which_ship' is not available.
* Otherwise, the number of ships that can be added is returned.
* CHECK_ALLIANCE:
* Test the alliance status of the race of 'which_ship'.
* Either GOOD_GUY (allied) or BAD_GUY (not allied) is returned.
* 0:
* Ally with the race of 'which_ship'. This makes their ship available
* for building in the shipyard.
* -1:
* End an alliance with the race of 'which_ship'. This ends the possibility
* of building their ships in the shipyard. For the Orz also the ships the
* player has with him will disappear.
* any other positive number:
* Give the player this much ships of type 'which_ship'. If it's
