* Replaced scheduler_remove_from_run_queue() by

scheduler_set_thread_priority(). Setting the thread priority was the
  only situation in which it was used.
* Renamed scheduler.cpp to scheduler_simple.cpp.
* The scheduler functions are no longer called directly. Instead there's
  an operation vector now, which is initialized at kernel init time.
  This allows for picking the most suitable scheduler for the machine
  (e.g. a non-SMP scheduler on a non-SMP machine).
