Stop using ntpdate(1) in our startup proceedure. Replace ntpdate(1) with

calls to ntpd -g.  ntpd is noticably slower than ntpdate, but is also more
accurate.  This removes the nasty hackery in rc.d/ntpdate that would parse
out ntp servers from /etc/ntp.conf (ntpd knows how to read its own config
file).  By default, ntpd *will* sync with its listed time servers.  To
turn this off so that ntpd does not sync, ntpd_sync_on_start="NO" can be
added to /etc/rc.conf.  If ntpd is not enabled (the default), then time is
not synced on startup.  ntpdate's use has been depreciated by the ntpd
authors for quite some time so this change shouldn't be unexpected.
