needed e.g. by "rcntp addserver".

* CVE-2016-2517, bsc#977455: remote configuration trustedkey/
requestkey/controlkey values are not properly validated.
* CVE-2016-2518, bsc#977457: Crafted addpeer with hmode > 7 causes array
wraparound with MATCH_ASSOC.

* integrate ntp-fork.patch
* Improve the fixes for: CVE-2015-7704, CVE-2015-7705, CVE-2015-7974
