1) Constify the xfrm_replay structures. From Julia Lawall
2) Protect xfrm state hash tables with rcu, lookups
can be done now without acquiring xfrm_state_lock.
From Florian Westphal.
3) Protect xfrm policy hash tables with rcu, lookups
can be done now without acquiring xfrm_policy_lock.
From Florian Westphal.
4) We don't need to have a garbage collector list per
namespace anymore, so use a global one instead.
From Florian Westphal.
