Allow readers to use RCU when reading Qemu timer lists. Applies to

This patch is for comment and review only. The rcu branch needs to be
rebased on upstream.
I'll certainly have a look through this. However before I do, what
problem is this trying to solve? Do we think there is possibility
of contention on the active timers lock? I used to think this was
taken (let alone contented) relatively infrequently, but Rob Herring's
recent email suggests to me the list is being modified in some
circumstances rather more frequently than I thought.
