Make sure "order none" RRset ordering rules are tested in the
"rrsetorder" system test just like all other rule types are. As the
check for the case of no "rrset-order" rule matching a given RRset also
tests "order none" (rather than "order random", as the test code may
suggest at first glance), replace the test code for that case so that it
matches other "order none" tests.
- all tests with "recursion yes" now also specify "dnssec-validation yes",
and all tests with "recursion no" also specify "dnssec-validation no".
this must be maintained in all new tests, or else validation will fail
when we use local root zones for testing.
- clean.sh has been modified where necessary to remove managed-keys.bind
and viewname.mkeys files.
- add CHANGES note
- update copyrights and license headers
- add -j to the make commands in .gitlab-ci.yml to take
advantage of parallelization in the gitlab CI process
