    task: Add task_set_essential
    
    Whenever a Hurd essential task crashes, startup just reboots the system
    since there's not much that can be done at that point. When we have a
    kernel debugger, however, we could at least get crashing information, so
    let's let Hurd's startup tell the kernel which tasks are essential, and
    trigger the debugger whenever they crash.
