commit    f9ab66c8cdb34ec4411985a20d34b533fdfaeea7

    Enhance SIGHLD handler of Pgpool-II main process.
    
    When Pgpool-II child is killed by SIGKILL signal, the SIGHLD handler
    just emitted LOG level message as other signals.  But SIGKILL is an
    important event, for example killed by OOM killer. So emit a WARNING
    level message instead.
    
    Per suggestion from Michail Alexakis.
