* nm_indirect_g_free:
* @arg: a pointer to a pointer that is to be freed.
*
* This does the same as nm_clear_g_free(arg) (g_clear_pointer (arg, g_free)).
* This is for example useful when you have a GArray with pointers and a
* clear function to free them. g_array_set_clear_func()'s destroy notify
* function gets a pointer to the array location, so we have to follow
* the first pointer.
