[patch] direct console set_status

[Kevin Kreamer]

Here is a patch enable setting DC_RAW via a device_set_status on the
console device.  While doing this code, I found that devio.c in 
hurd/daemons calls this function with the TTY_* flavors, hence their
inclusion here.

No changelog yet, as I am not sure how done I am.  I'll continue 
working on that user-space console Marcus was talking about.

Invocation:
        mach_port_t master;
        kern_return_t err;
        mach_port_t console;
        
        err = get_privileged_ports(NULL, &master);
        if (err)
          return err;
        err = device_open(master, D_READ, "console", &console);
        if (err)
          return err;
        mach_port_deallocate(mach_task_self(), master);
        
        err = device_set_status(console, DC_RAW, 0, 0);
        if (err)
          return err;

        /* console stuff here */

        err = device_set_status(console, DC_NO_ONLCR, 0, 0);
        if (err)
          return err;

Thanks,
Kevin
