To reduce the amount of log spam when root servers change their
addresses keep a table of upcoming changes by expected date and time
and suppress reporting differences for them until then.
Add initial entry for B.ROOT-SERVERS.NET, Nov 27, 2023.
(cherry picked from commit b69100b747)
This covers both root hints and the default primaries for the root
zone mirror. The official change date is Nov 27, 2023.

Add a GitLab CI job that is only run for tags and makes signing BIND 9
releases more convenient by utilizing a signing VM that is registered as
a GitLab CI runner. This pulls the signing process into the release
pipelines in GitLab CI, resulting in job artifacts containing the
signatures for BIND 9 releases, which in turns simplifies the subsequent
release publication steps.

When serve-stale is enabled and recursive resolution fails, the fallback
to lookup stale data always happens in the cache database. Any
authoritative data is ignored, and only information learned through
recursive resolution is examined.
If there is data in the cache that could lead to an answer, and this can
be just the root delegation, the resolver will iterate further, getting
closer to the answer that can be found by recursing down the root, and
eventually puts the final response in the cache.
Change the fallback to serve-stale to use 'query_getdb()', that finds
out the best matching database for the given query.
(cherry picked from commit 2322425016)
Add a test case where serve-stale is enabled on a server that also
servers a local authoritative zone.
The particular case tests a lame delegation and checks if falling
back to serving stale data does not attempt to retrieve the query
by recursing from the root down.

The bash implementation on MacOS 13.6.1 is:
% /bin/sh --version
GNU bash, version 3.2.57(1)-release (arm64-apple-darwin22)
Copyright (C) 2007 Free Software Foundation, Inc.
This fails to handle 'case' inside of $(). Reimplement using
if/elif/fi.
Move the declaration of 'engine' within the appropriate #if/#endif
block. Remove the UNUSED(engine) from the #else block.

All changes in this commit were automated using the command:
shfmt -w -i 2 -ci -bn bin/tests/system/ util/ $(find bin/tests/system/ -name "*.sh.in")
By default, only *.sh and files without extension are checked, so
*.sh.in files have to be added additionally. (See mvdan/sh#944)

Ubuntu 18.04 LTS (Bionic Beaver) is EOL.
Move gcc:bionic:amd64-specific CFLAGS and EXTRA_CONFIGURE to
gcc:jammy:amd64.
(cherry picked from commit 6d100c4a32)
Basically all local data is considered trusted, and proper ACLs and
limits need to be explicitly configured. We are also free to let
protocol non-compliant servers burn in flames.

Building the PDF version of the BIND 9 ARM requires TeX Live to be
present on the build host. A TeX Live installation takes up several
gigabytes of disk space. This significantly increases the size of the
Debian Docker images that include that toolchain, even though only two
GitLab CI jobs actually use it.
Instead of including TeX Live in the Docker image itself, install the
former on demand in a new GitLab CI job that only tests building the PDF
version of the BIND 9 ARM. Do the same for qpdf, a tool used for
checking the PDF output produced by TeX Live. This enables the size of
the "base" Docker image (which a lot of GitLab CI jobs need to pull) to
remain within reasonable limits. As downloading and installing TeX Live
takes a significant amount of time, only run the new job in scheduled
pipelines and for tags. Adjust job dependencies so that the "release"
job continues to work.
(cherry picked from commit 29cba33d44)
The autoscaling GitLab CI runners currently used for most GitLab CI jobs
spin up AWS EC2 instances that are at least as powerful as the dedicated
instances used for running "stress" tests. Move all Linux-based
"stress" tests to autoscaling GitLab CI runners to enable deprovisioning
Linux AWS instances reserved for running "stress" tests. Leave FreeBSD
"stress" tests intact as there is currently no support for autoscaling
BSD instances.
(cherry picked from commit 12ea994680)
In BIND 9.16, we don't need to run autoreconf, because ./configure et
al. are part of the source tree. It's nothing more than a check to see
if the build configuration can be built.
'rndc thaw' initiates asynchrous loading of all the zones
similar to 'rndc load'. Wait for the test zone's load to
complete before testing that it is updatable again.
