rcu: Add RCU CPU stall notifier

It is sometimes helpful to have a way for the subsystem causing
the stall to dump its state when an RCU CPU stall occurs.  This
commit therefore bases rcu_stall_chain_notifier_register() and
rcu_stall_chain_notifier_unregister() on atomic notifiers in order to
provide this functionality.
