    Kernel - replace unbounded uses of kvcprintf() and reduce stack use by devfs
    
    * Replace unbounded uses of kvcprintf() to guarantee that buffers do not
      overflow.
    
    * Do not declare PATH_MAX buffers on the stack.  Use kvasnrprintf() or
      kmalloc() to allocate space.
    
    * In make_autoclone_dev() fix an improper use of a buffer passed as the
      fmt argument to make_dev().
