    Add support for setting coresize from sysconfig.
    
    Add support for using this if it is defined by the administrator
    in the /etc/sysconfig/varnish file.
    
    From way back we've had a commented-out DAEMON_COREFILE_LIMIT in
    our /etc/sysconfig/varnish file, which wasn't referenced anywhere.
