    pluto: sprinkle const on struct spd_route and related tidying
    
    To make the data-flow clearer:
    
    - sprinkle const, starting with struct spd_route
    
    - combine declaration of autos with initialization
    
    - minimize scope of autos
    
    - delete unused sysdep functions (do_command_*)
    
    - remove redundant const from struct_desc objects
