    pluto: tidy kernel_netlink.c's send_netlink_msg function
    
    - make a universal type for the record returned by netlink
    
    - replace confusing way that the expected result type is passed to
    
    - highlight declaration of a static local since this is odd
    
    - replace tricky use of errno as a result
    
    - reduce scope of some local variables
    
    - fix some length modifiers in format strings
    
    - get rid of the GOTO from netlink_process_raw_ifaces
