Determines the next item type of a tuple or dictionary entry
type.
type must be the result of a previous call to
g_variant_type_first() or g_variant_type_next().
If called on the key type of a dictionary entry then this call
returns the value type. If called on the value type of a dictionary
entry then this call returns NULL.
For tuples, NULL is returned when type is the last item in a tuple.
