Calls the given function for each data element which is associated
with the given location. Note that this function is NOT thread-safe.
So unless dataset_location can be protected from any modifications
during invocation of this function, it should not be called.
func can make changes to the dataset, but the iteration will not
reflect changes made during the glib.global.datasetForeach call, other
than skipping over elements that are removed.
