    Gio::DataInputStream: Disable deprecation warnings from glib
    
    g_data_input_stream_read_until(), _read_until_async() and _read_until_finish()
    have been deprecated in glib/gio. They can't be deprecated in the stable
    glibmm-2-54 branch now. This patch makes it possible to build glibmm-2.54.x
    against the newest glib.
