Using ntpd in multicast client is easy to configure but you still need
to adjust $ntpdate_hosts if you want ntpdate to be run.
The proposed patch makes /etc/rc.d/ntpdate able to take use of 
the 'multicastclient' client setting from /etc/ntp.conf so setting
$ntpdate_hosts is no more required in an "all" multicast NTP setup.
Both default value of NTP.MCAST.NET and custom multicast address are suported.
