Pushes other iterator onto it. All calls performed on it are
forwarded to other. If other returns GST_ITERATOR_DONE, it is
popped again and calls are handled by it again.
This function is mainly used by objects implementing the iterator
next function to recurse into substructures.
When Iterator.resync is called on it, other will automatically be
popped.
