* 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.
