dc8c5823d3 Tighten default restrictions for ntpd(8) server and provide a link
to NTP access restriction documentation.

The new default restrictions would allow only time queries from a
remote system and will KoD all other requests, but still allow
localhost to do make all requests.

These restrictions are also recommended for all Internet-facing
public NTP servers.

This changeset is intended for an instant MFC to stable/10 and
releng/10.0.

784ae71960 1) Use our vendor domain at the pool.
2) Point people at the pool website and encourage
   people to provide a server in the pool (as a
   courtesy to the pool guys).
3) Fix a spelling.
4) Comment out the local clock and include a link
   to documentation for use of the local clock on
   the ntp.org site.

10233cbb4a Welcome to a default installed /etc/ntp.conf
This NTP configuration file points to the [012].pool.ntp.org servers,
which will return a list of geographical local NTP servers.
It uses the best-practice options of "iburst" and "maxpoll 9".
It gives examples on how to use the "restrict" commands, which are
unfortunately not working when you use the pool.ntp.org servers.
It sets up a fudge server so any clients syncing against this server
will always be synced even if we lose the master.

The idea of this file was briefly discussed on -net.
