Another option would be to have a function like that to create a wrapper around
the original iterator, then we can use all of the existing functions, a bit
like gst_iterator_filter() works:
GstIterator *gst_iterator_once (GstIterator *iter);

I'm not a big fan of having special functions to iterate pads or elements,
maybe a generic one for GObjects? Then just have something like
gst_iterator_foreach_object()?
