Reads a child item out of a container #GVariant instance. This
includes variants, maybes, arrays, tuples and dictionary
entries. It is an error to call this function on any other type of
#GVariant.
It is an error if @index_ is greater than the number of child items
in the container. See g_variant_n_children().
The returned value is never floating. You should free it with
g_variant_unref() when you're done with it.
