thread: simplify the scheduler
need_schedule was no longer used by anything else, and schedule_lock
only verified if we were being called from inside sched_hook_func().
Make the localness of this data explicit.
While we're at it, call kaboom if we ever find ourselves without a
runnable thread (which should not be possible, as the idle thread is
not allowed to block.)
