Add convenience API that iterates over all pads, sink pads or source pads and makes sure that the foreach function is called exactly once for each pad. This is a KISS implementation. It doesn't use GstIterator and doesn't try to do clever things like resync if pads are added or removed while the function is executing. We can still do that in future if we think it's needed, but in practice it will likely make absolutely no difference whatsoever, since these things will have to be handled properly elsewhere by the element anyway if they're important. After all, it's always possible that a pad is added or removed just after the iterator finishes iterating, but before the function returns. This is also a replacement for gst_aggregator_iterate_sink_pads(). https://bugzilla.gnome.org/show_bug.cgi?id=785679
