    Gio::TlsClientConnection: Disable deprecation warnings from glib
    
    g_tls_client_connection_[set|get]_use_ssl3() and the use-ssl3 property
    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.
