    socket: Properly inherit AUTOLOWAT and AUTOSIZE from listen socket
    
    The soreserve and pru_attach could set these two flags internally,
    so the original code will only retain those two flags but not clear
    them if the listen socket does not have them.  We now explicitly
    check those two flags and then set or clear them accordingly.
