The digdelv system test has a test case in which stderr was
included in the dig output. When trace logging was in use,
this confused the grep and caused a spurious test failure.

Update the 'catz' system test by adding tests that update an
catalog zone (catalog1.example) while preserving existing entries
(increase SOA serial) then check that catalog zone has transferred
and that the existing entries have not accidentally been removed
as a consequence (can return updated zone content).
(cherry picked from commit bf9c569852)
After receiving a new version of a catalog zone it is required
to merge it with the old version.
The algorithm walks through the new version's hash table and applies
the following logic:
1. If an entry from the new version does not exist in the old
version, then it's a new entry, add the entry to the `toadd` hash
table.
2. If the zone does not exist in the set of configured zones, because
it was deleted via rndc delzone or it was removed from another
catalog zone instance, then add into to the `toadd` hash table to
be reinstantiated.
3. If an entry from the new version also exists in the old version,
but is modified, then add the entry to the `tomod` hash table, then
remove it from the old version's hash table.
4. If an entry from the new version also exists in the old version and
is the same (unmodified) then just remove it from the old version's
hash table.
The algorithm then deletes all the remaining zones which still exist
in the old version's hash table (because only the ones that don't
exist in the new version should now remain there), then adds the ones
that were added to the `toadd`, and modifies the ones that were added
to the `tomod`, completing the merge.
During a recent refactoring, the part when the entry should be
removed from the old version's hash table on condition (4.) above
was accidentally omitted, so the unmodified zones were remaining
in the old version's hash table and consequently being deleted.

With custom fstrm library in the Fedora image which uses mutexes instead
of barriers ThreadSanitizer suppression with GCC is not necessary

For the sake of running ASAN and TSAN jobs with the latest stable GCC,
replace "base image" (Debian Buster with GCC 8.3.0) with Fedora 34 image
with GCC 11.

It was found, that the original commit adding the setmodtime() was
incompletely squashed and there was double check for
DNS_ZONEFLG_NEEDDUMP instead of check for DNS_ZONEFLG_NEEDDUMP and
DNS_ZONEFLG_DUMPING.
Change the duplicate check to DNS_ZONEFLG_DUMPING.

The isc_time_add() and isc_time_subtract() didn't have a unit test, add
the unit test with couple of edge case vectors to check whether overflow
and underflow is correctly handled.
(cherry picked from commit 04511736a0)
The isc_time_add() could overflow when t.seconds + i.seconds == UINT_MAX
and t.nanoseconds + i.nanoseconds >= NS_PER_S.
Fix the overflow in isc_time_add(), and simplify the ISC_R_RANGE checks
both in isc_time_add() and isc_time_subtract() functions.

The qmin system test was printing spurious output. On investigation,
the test case turned out to be both broken and ineffective: its
expectations were wrong, and it was printing the output because its
wrong expectations were not met, and those failed expectations were
not causing a test failure. All of this has been corrected.

The ReferenceRole class is only available in Sphinx >= 2.0.0, which
makes building BIND 9 documentation impossible with older Sphinx
versions:
Running Sphinx v1.7.6
Configuration error:
There is a programable error in your configuration file:
Traceback (most recent call last):
File "/usr/lib/python3.6/site-packages/sphinx/config.py", line 161, in __init__
execfile_(filename, config)

exec_(code, _globals)
File "conf.py", line 21, in <module>
from sphinx.util.docutils import ReferenceRole
ImportError: cannot import name 'ReferenceRole'
Work around the problem by defining a stub version of the ReferenceRole
class if the latter cannot be imported. This allows documentation
(without GitLab hyperlinks in release notes) to be built with older
Sphinx versions.

The autoconf script prints used compiler version at the end of the
configure script. Solaris native compiler doesn't support --version,
and -V has to be used which in turn isn't supported by Gcc/Clang.
Detect which version flag has to be used and call $CC with it.

The 55636ab5 commit made some changes in the reference manual
regarding catalog zones which do not actually correspond to reality
for the v9_16 branch.
This commit reverts those changes.
The 'listenlist_test', 'notify_test', and 'query_test' tests failed
when the descriptor limit was 256 on MacOS 11.6 with 8 cpus. On the
test platform the limit needed to be increased to ~400. Increase
the limit to at least 1024 to give some head room.

Previously a missing/deleted zone which was referenced by a catalog
zone was causing a crash when doing a reload.
This commit will make `named` to ignore the fact that the zone is
missing, and make sure to restore it later on.
(cherry picked from commit 94a5712801)
zone.c:integrity_checks() acquires a read lock while iterating the
zone database, and calls zone_check_mx() which acquires another
read lock. If another thread tries to acquire a write lock in the
meantime, it can deadlock. Calling dns_dbiterator_pause() to release
the first read lock prevents this.
