rcu-tasks: Make rcu_barrier_tasks*() handle multiple callback queues ...
Currently, rcu_barrier_tasks(), rcu_barrier_tasks_rude(),
and rcu_barrier_tasks_trace() simply invoke the corresponding
synchronize_rcu_tasks*() function. This works because there is only
one callback queue.
However, there will soon be multiple callback queues. This commit
therefore scans the queues currently in use, entraining a callback on
each non-empty queue. Sequence numbers and reference counts are used
to synchronize this process in a manner similar to the approach taken
by rcu_barrier().
