    Socket's implementation of ref_state_set to return empty sets instead of NULL
    
    Calls to atk_object_ref_state_set() are expected to return a valid
    state set always, so it would be better if this implementation of
    socket's ref_state_set() returned empty sets instead of just NULL, to
    avoid calling to atk_state_set_*() functions over invalid instances of
    AtkStateSet (e.g. add_pending_items() in accessible-cache.c).
