Ondřej Surý 086b63f56d Use isc_queue to implement wait-free deadnodes queue 
Replace the ISC_LIST based deadnodes implementation with isc_queue which
is wait-free and we don't have to acquire neither the tree nor node lock
to append nodes to the queue and the cleaning process can also
copy (splice) the list into a local copy without acquiring the list.

Currently, there's little benefit to this as we need to hold those
locks anyway, but in the future as we move to RCU based implementation,
this will be ready.

To align the cleaning with our event loop based model, remove the
hardcoded count for the node locks and use the number of the event loops
instead.  This way, each event loop can have its own cleaning as part of
the process.  Use uniform random numbers to spread the nodes evenly
between the buckets (instead of hashing the domain name).
