Subject: startup: Make essential tasks essential to mach
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 make Hurd's startup tell the kernel which tasks are essential, so
it can trigger the debugger whenever they crash.
