* Change 'dns_catz_new_zones()' function's prototype (the order of the
arguments) to synchronize it with the similar function in rpz.c.
* Rename 'refs' to 'references' in preparation of ISC_REFCOUNT_*
macros usage for reference tracking.
* Unify dns_catz_zone_t naming to catz, and dns_catz_zones_t naming to
catzs, following the logic of similar changes in rpz.c.
* Use C compound literals for structure initialization.
* Synchronize the "new zone version came too soon" log message with the
one in rpz.c.
* Use more of 'sizeof(*ptr)' style instead of the 'sizeof(type_t)' style
expressions when allocating or freeing memory for 'ptr'.

Make OpenBSD system tests more stable by disabling parallelism in CI.
Accordingly, they will run 3-4 times longer.
(cherry picked from commit d73eba57bd)
Setting TEST_PARALLEL_JOBS to 4 in FreeBSD system test jobs is a no-op
because it's already set to 4, one level above, on the global level.

Add new SonarCloud GitHub Action and configuration; something (maybe
the way the builds were submitted) has apparently changed and the
project got deleted and the analysis wasn't working.

[9.18][CVE-2022-3924] Add a reproducer for the serve-stale crash when recursive clients soft quota is reached
See merge request isc-projects/bind9!7576
Reproduce the assertion by configuring a 'named' resolver with
'recursive-clients 10;' configuration option and running 20
queries is parallel.
Also tweak the 'ans2/ans.pl' to simulate a 50ms network latency
when qname starts with "latency". This makes sure that queries
running in parallel don't get served immediately, thus allowing
the configured recursive clients quota limitation to be activated.

The kasp pointers in dns_zone_t should consistently be changed by
dns_kasp_attach and dns_kasp_detach so the usage is balanced.
(cherry picked from commit b41882cc75)
When switching to a new view during a reconfiguration (or reverting
to the old view), detach the 'rpzs' and 'catzs' from the previuos view.
The 'catzs' case was earlier solved slightly differently, by detaching
from the new view when reverting to the old view, but we can not solve
this the same way for 'rpzs', because now in BIND 9.19 and BIND 9.18
a dns_rpz_shutdown_rpzs() call was added in view's destroy() function
before detaching the 'rpzs', so we can not leave the 'rpzs' attached to
the previous view and let it be shut down when we intend to continue
using it with the new view.
Instead, "re-fix" the issue for the 'catzs' pointer the same way as
for 'rpzs' for consistency, and also because a similar shutdown call
is likely to be implemented for 'catzs' in the near future.

The faulty "DLZ" configuration triggers a reconfiguration failure
in such a place where view reverting code is covered.

this function was just a front-end for gethostname(). it was
needed when we supported windows, which has a different function
for looking up the hostname; it's not needed any longer.

bin/tests/system/get_algorithms.py:225:4: R1720: Unnecessary "else" after "raise", remove the "else" and de-indent the code inside it (no-else-raise)
(cherry picked from commit 8064ac6bec)
Free/detach tsigkey and sig0key when exiting and then call
dst_lib_destroy if we have previously called dst_lib_init. This will,
in theory, allow OPENSSL_cleanup to free all memory.

Include MD5 feature detection in featuretest tool and use it in some
places. When RHEL distribution or Fedora ELN is in FIPS mode, then MD5
algorithm is unavailable completely and even hmac-md5 algorithm usage
will always fail. Work that around by checking MD5 works and if not,
skipping its usage.
Those changes were dragged as downstream patch bind-9.11-fips-tests.patch
in Fedora and RHEL.

Tests using diff to compare outputs of dig +short shall ignore lines
starting with ";". In dig +short output, such lines should only be
present for errors such as network issues. Since we utilize dig's
default timeout/retry mechanisms, these transitory issues should be
ignored and only the final output should be considered during the diff
comparison.

A dns_rpz_unref_rpzs() call is missing when taking the 'goto unlock;'
path on shutdown, in order to compensate for the earlier
dns_rpz_ref_rpzs() call.
Move the dns_rpz_ref_rpzs() call after the shutdown check.
