First the iterator is advanced to the next (possibly first) attribute.
If that fails, then FALSE is returned and there are no other
effects.
If successful, name and value are set to the name and value of the
attribute that has just been advanced to. At this point,
Menu.attributeIterGetName and Menu.attributeIterGetValue will
return the same values again.
The value returned in name remains valid for as long as the iterator
remains at the current position. The value returned in value must
be unreffed using Variant.unref when it is no longer in use.
This function combines Menu.attributeIterNext with Menu.attributeIterGetName and Menu.attributeIterGetValue.
