* workqueue.h: Add a WQ_QUEUE_BLOCKED item_status return code,
to allow a queue function to indicate the queue is not
ready/blocked - rather than any problem with the item at hand.
Add a notion of being able to 'plug' and 'unplug' a queue.
Add helpers to plug/unplug a queue.
Add a completion callback, to be called when a queue is emptied.
* workqueue.c: (work_queue_new) remove useless list_free.
(work_queue_schedule) new internal helper function to schedule
queue, if appropriate.
(work_queue_add) use work_queue_schedule
(show_work_queues) Print 'P' if queue is plugged.
(work_queue_plug) new API function, plug a queue - ie prevent it
from 'drained' / processed / scheduled.
(work_queue_unplug) unplug a queue, allowing it to be drained
/ scheduled / processed again.
(work_queue_run) Add support for WQ_QUEUE_BLOCKED.
Add comment for RETRY_NOW case.
Make hysteris more aggresive in ramping up granularity, improves
performance significantly.
Add support for calling completion callback when queue is emptied,
possibly useful for knowing when to unplug a queue.
