Mathieu Desnoyers 1c50b728c3 rcu: add rcu_read_lock_sched() / rcu_read_unlock_sched() ...

Add rcu_read_lock_sched() and rcu_read_unlock_sched() to rcupdate.h to match the
recently added write-side call_rcu_sched() and rcu_barrier_sched(). They also
match the no-so-recently-added synchronize_sched().

It will help following matching use of the update/read lock primitives. Those
new read lock will replace preempt_disable()/enable() used in pair with
RCU-classic synchronization.
