When converting this code to use the list macros, I changed it so objects are
added to the head of a bucket instead of the tail.  However, while looking over
code with mmichelson, we noticed that the algorithm used in ao2_iterator_next
requires that items are added to the tail.  This wouldn't have caused any huge
problem, but it wasn't correct.  It meant that if an object was added to a
container while you were iterating it, and it was added to the same bucket that
the current element is in, then the new object would be returned by 
ao2_iterator_next, and any other objects in the bucket would be bypassed in
the traversal.
