Subject: [PATCH] Add a system test for mixed-case data for the same owner
We were missing a test where a single owner name would have multiple
types with a different case. The generated RRSIGs and NSEC records will
then have different case than the signed records and message parser have
to cope with that and treat everything as the same owner.
(cherry picked from commit a114042059ecbbc94ae0f604ca681323a75af480)
(cherry picked from upstream commit b9c10a194da3358204f5ba7d91e55332db435614)
