Add default definition for configUSE_QUEUE_SETS.

Browse Source 
Add eTaskConfirmSleepModeStatus() (not yet tested).
Only call prvQueueUnregisterQueue() when a queue or semaphore is deleted if configQUEUE_REGISTRY_SIZE > 0.
Back out change that checks the configUSE_PORT_OPTMISED_TASK_SELECTION value before uxPriorityUsedOnEntry is set in vTaskPrioritySet as it generated more warnings (with other compilers) than it fixed.
