Moved PollableCondition, PollableQueue and to sys. Fixed cluster shutdown issues.

sys/PollableCondition: is a generic mechansim to poll for non-IO
events in the Poller.

sys/PollableQueue: is a thread-safe queue template that can be
dispatched from the Poller when there are items on the queue. It uses
PollableCondition.
