Paul E. McKenney 70f12f848d rcu: add rcu_barrier_sched() and rcu_barrier_bh() ...

Add rcu_barrier_sched() and rcu_barrier_bh().  With these in place,
rcutorture no longer gives the occasional oops when repeatedly starting
and stopping torturing rcu_bh.  Also adds the API needed to flush out
pre-existing call_rcu_sched() callbacks.
