Please all welcome the long-awaited upgrade from our ancient xntpd 3.4f

to a brand new and shiny ntpd 4.0.98f.

I got tired of waiting for 4.1.0 and there is the feature freeze deadline
so here it is. This is the contrib/ part of the upgrade. The Makefile glue
will be added very soon in usr.sbin.

It builds and runs on both i386 and alpha (Thanks Peter!).

The bad news is that manpages no longer exist, everything is in HTML. I'll
commit the text version of each HTML file in /usr/share/doc/ntp soon to have
at least the help files w/o needing to get the entire contrib/ntp tree.

I'll commit FREEBSD-Xlist as soon as I can skip over $FreeBSD$ checks...

+NTP 4.0.98f
+	originals can be found on ftp://louie.udel.edu/pub/ntp/testing
+
+For the import of NTP the following files were removed:
+
+	ports/*				NT files
+	html/pic/*			GIF files
+
+The stripped down version was created using FREEBSD-Xlist during extraction:
+
+	tar -X FREEBSD-Xlist -xvzf ntp-4.0.98f.tar.gz
+	mv ntp-4.0.98f ntp
+
+Imported by:
+
+	cvs import -m 'Virgin import of ntpd 4.0.98f' \
+		src/contrib/ntp DMILLS v4_0_98f
+
+config.h was generated by running configure and excluding almost all clock
+drivers (what is included is DCF77 -- what I use -- and local clocks).
+
+The file is then edited to edit the value of "NO_PARENB_IGNPAR" because we
+need to set no parity on the serial port (needed for DCF77). All clock
+drivers are then disabled (some of them are included by default by ntpd).
+
+Note that there are two #ifdef to support both alpha and i386 from the same
+sources. They'll need to be redone for each upgrade to the vendor branch to
+keep config.h in sync.
+
+Documentation in /usr/share/doc/ntp is generated from the HTML files with
+lynx (without the GIF files of course).
