srcu: Add size-state transitioning code
This is just dead code at the moment, and will be used once
the state-transition code is activated.
Because srcu_barrier() must be aware of transition before call_srcu(), the
state machine waits for an SRCU grace period before callbacks are queued
to the non-CPU-0 queues. This requres that portions of srcu_barrier()
be enclosed in an SRCU read-side critical section.
