Processor affinity for processes.

 - Split up run queues so that every cpu has one.
 - Make setrunqueue choose the cpu where we want to make this process
   runnable (this should be refined and less brutal in the future).
 - When choosing the cpu where we want to run, make some kind of educated
   guess where it will be best to run (very naive right now).
Other:
 - Set operations for sets of cpus.
 - load average calculations per cpu.
 - sched_is_idle() -> curcpu_is_idle()
