srcu: Fill out polled grace-period APIs

This commit adds the get_completed_synchronize_srcu() and the
same_state_synchronize_srcu() functions.  The first returns a cookie
that is always interpreted as corresponding to an expired grace period.
The second does an equality comparison of a pair of cookies.
