Switching to OpenNTPD

[Matthew Dillon]

:Hi all,
:the attached patch switches from ntp.org's ntpd to OpenNTPD. This means:
:...
: smmsp:*:25:
: authpf:*:63:
:+_pflogd:*:64:
:+_ntp:*:65:
 
    You have to add the various uid and groupd id requirements to
    the buildworld/installworld requirements check, too.

    Ok, now we really *do* need to make 'make upgrade' do the right
    thing, and perhaps even have a 'make preupgrade' target as well.
    If it doesn't already have the feature can't we just have an option 
    to adduser that conditionally adds a user with a specified uid,
    but does nothing if the user already exists?

    We also need an addgroup command with the same capability.
