fix thread migration code (i.e., sched_setaffinity())
...
- moved migration code into idle() process and updated schedule() to detect
when a thread has moved to another CPU in order to avoid doing housekeeping
on behalf of the original one
- start CPU head from core 0
- keeps track of nested interrupts
