Reconnection and PS4 authentication helpers

reconnection-and-auth.gpc

int auth_status;

main {
    auth_status = ps4_authtimeout();

    if(event_press(PS5_OPTIONS)) {
        output_reconnection();
    }
}

ps4_authtimeout is retained by Live but has limited relevance on current firmware. Reconnection is a device-impacting action; guard it behind an explicit event and test on the exact output protocol.
