[PATCH] update to NTP in base

Hello!
The instructions at
http://www.freebsd.org/cgi/query-pr.cgi?pr=148836
(Pr bin/148836) contains an update to the base system NTP program suite. 
Please test it and report successes and failures.
Known issues: The html doc distribution is not installed, but it can be 
found on the internet if needed. If it is requested by many to include 
it I'll make a new patch for it.

The patch can be found here
http://www.lysator.liu.se/~zeising/FreeBSD/ntp-update/ntpupdate.diff 
(uncompressed, 10M)
http://www.lysator.liu.se/~zeising/FreeBSD/ntp-update/ntpupdate.diff.bz2 
(compressed with bz2, 1.7M)
The reason for the sizes is that the patches include a lot of changes to 
the vendor code. See the PR for details.

Best Regards!
