* simpler methods of blocking on multiple objects.
*
* Note 2: Blocking on a queue set that contains a mutex will not cause the
* mutex holder to inherit the priority of the blocked task.
*
* Note 3: An additional 4 bytes of RAM is required for each space in a every
* queue added to a queue set. Therefore counting semaphores that have a high
* maximum count value should not be added to a queue set.
*
* Note 4: A receive (in the case of a queue) or take (in the case of a
* semaphore) operation must not be performed on a member of a queue set unless
* a call to xQueueSelectFromSet() has first returned a handle to that set member.
*
* @param uxEventQueueLength Queue sets store events that occur on
* the queues and semaphores contained in the set. uxEventQueueLength specifies
* the maximum number of events that can be queued at once. To be absolutely
* certain that events are not lost uxEventQueueLength should be set to the
* total sum of the length of the queues added to the set, where binary
* semaphores and mutexes have a length of 1, and counting semaphores have a
* length set by their maximum count value. Examples:
* + If a queue set is to hold a queue of length 5, another queue of length 12,
* and a binary semaphore, then uxEventQueueLength should be set to
* (5 + 12 + 1), or 18.
* + If a queue set is to hold three binary semaphores then uxEventQueueLength
* should be set to (1 + 1 + 1 ), or 3.
* + If a queue set is to hold a counting semaphore that has a maximum count of
* 5, and a counting semaphore that has a maximum count of 3, then
* uxEventQueueLength should be set to (5 + 3), or 8.
*
* @return If the queue set is created successfully then a handle to the created
* queue set is returned. Otherwise NULL is returned.
