* CPUs can now be disabled - that is, they will keep idling.

Browse Source 
* Added syscalls _kern_set_cpu_enabled() and _kern_cpu_enabled().
* scheduler.c::sRunQueue::tail was not maintained at all; changed sRunQueue to
  be a simple thread pointer instead of a struct thread_queue.
* Turns out we're monitoring CPU activity incorrectly when we've got more
  than one CPU.
* Renamed the global CPU array from "cpu" to gCPU.
