Update our ntpd to the long awaited 4.2.0 version.
This bring us several things:
- updated drivers
- IPv6 support at last
- ntp-genkeys is replaced by ntp-keygen
- ntptrace is now a script (courtesy of John Hay)
- lots of renamed files from .htm to .html (while I prefer .html, I
find the change a bit gratuitous)
- still no manpages :(
Please test and report.
Commit very much helped by: GNU arch (http://gnuarch.org/)
