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 gst_iterator_resync() is called on @it, @other will automatically be
popped.
