Doug Barton eda14e83f2 Upgrade to version 9.6.2. This version includes all previously released
security patches to the 9.6.1 version, as well as many other bug fixes.

This version also incorporates a different fix for the problem we had
patched in contrib/bind9/bin/dig/dighost.c, so that file is now back
to being the same as the vendor version.

Due to the fact that the DNSSEC algorithm that will be used to sign the
root zone is only included in this version and in 9.7.x those who wish
to do validation MUST upgrade to one of these prior to July 2010.
