Make sure the CYGWIN environment variable is set whenever system tests
are run on Windows to prevent stop.pl from making incorrect assumptions
about the environment it is running in, which triggers e.g. false
reports about named instances crashing on shutdown when system tests are
run on Windows. This issue has not been caught earlier because the
CYGWIN environment variable was incidentally being set on a higher level
in our Windows test environments.
Error reporting for parallel system tests on Windows has been broken all
along: since all parallel.mk targets generated by parallel.sh pipe their
output through "tee", the return code from run.sh is lost and thus
running "make -f parallel.mk check" will not yield a non-zero return
code if some system tests fail. The same applies to runsequential.sh.
Yet, runall.sh on Windows only sets its return code to a non-zero value
if either "make -f parallel.mk check" or runsequential.sh returns a
non-zero return code. Fix by making runall.sh yield a non-zero return
code when testsummary.sh fails, which is the same approach as the one
used in the "test" target in bin/tests/system/Makefile.

Until now, the build process for BIND on Windows involved upgrading the
solution file to the version of Visual Studio used on the build host.
Unfortunately, the executable used for that (devenv.exe) is not part of
Visual Studio Build Tools and thus there is no clean way to make that
executable part of a Windows Server container.
Luckily, the solution upgrade process boils down to just adding XML tags
to Visual Studio project files and modifying certain XML attributes - in
files which we pregenerate anyway using win32utils/Configure. Thus,
extend win32utils/Configure with three new command line parameters that
enable it to mimic what "devenv.exe bind9.sln /upgrade" does. This
makes the devenv.exe build step redundant and thus facilitates building
BIND in Windows Server containers.

Build configuration for the dnssec-cds Visual Studio project is absent
from the solution file template, which means the solution needs to be
upgraded using "devenv bind9.sln /upgrade" in order for the dnssec-cds
project to be built. Add the build configuration for dnssec-cds to the
solution file template so that upgrading the solution is not necessary
for building that project.

named-checkzone does not use libbind9. Update the Visual Studio project
file template for named-checkzone to reflect that, thus preventing
compilation issues during parallel builds.
(cherry picked from commit 918ebd9830)
When commit 8eb88aafee removed liblwres,
it also modified nsupdate to use libirs instead of liblwres, but the
Visual Studio project files were not updated to reflect that change.
Make sure the nsupdate Visual Studio project depends on the libirs
project to prevent compilation issues during parallel builds.

Make stderr fully buffered on Windows to improve named performance when
it is logging to stderr, which happens e.g. in system tests. Note that:
- line buffering (_IOLBF) is unavailable on Windows,
- fflush() is called anyway after each log message gets written to the
default stderr logging channels created by libisc.

BIND system tests are run in a Cygwin environment. Apparently Cygwin
shell sets the SEM_NOGPFAULTERRORBOX bit in its process error mode which
is then inherited by all spawned child processes. This bit prevents the
Windows Error Reporting dialog from being displayed, which I assume is
part of an effort to contain memory handling errors triggered by Cygwin
binaries in the Cygwin environment. Unfortunately, this also prevents
automatic crash dump creation by Windows Error Reporting and Cygwin
itself does not handle memory errors in native Windows processes spawned
from a Cygwin shell.
Fix by clearing the SEM_NOGPFAULTERRORBOX bit inside named if it is
started in a Cygwin environment, thus overriding the Cygwin-set process
error mode in order to enable Windows Error Reporting to handle all
named crashes.

When libxml2 is to be used in a multi-threaded application, the
xmlInitThreads() function must be called before any other libxml2
function. This function does different things on various platforms and
thus one can get away without calling it on Unix systems, but not on
Windows, where it initializes critical section objects used for
synchronizing access to data structures shared between threads. Add the
missing xmlInitThreads() call to prevent crashes on affected systems.
Also add a matching xmlCleanupThreads() call to properly release the
resources set up by xmlInitThreads().

Addresses the database changing w/o the changes being done under task lock.
Fix: build the database before assigning it to the zone.

No problems have been observed on the FreeBSD GitLab CI runner during
the burn-in period, when FreeBSD jobs needed to be triggered manually.
Thus, make the FreeBSD jobs run automatically along other GitLab CI
jobs.

`/usr/share/sgml/docbook/xsl-stylesheets` and `/usr/share/dblatex` are
places where docbook-style-xsl and, respectively, dblatex packages on
Red Hat systems put their XSL templates. Unless we hint this place it
has to be added to `./configure` manually (`--with-docbook-xsl=...`):

Ensure BIND can be tested on FreeBSD in GitLab to more quickly catch
build and test errors on that operating system. Make the relevant jobs
optional until the CI environment supporting them is deemed stable
enough for continuous use.
FreeBSD jobs are run using the Custom executor feature of GitLab Runner.
Unlike the Docker executor, the Custom executor does not support the
"image" option and thus some way of informing the runner about the OS
version to use for a given job is necessary. Arguably the simplest way
of doing that without a lot of code duplication in .gitlab-ci.yml would
be to use a YAML template with a "variables" block specifying the
desired FreeBSD release to use, but including such a template in a job
definition would cause issues in case other variables also needed to be
set for that job (e.g. CFLAGS or EXTRA_CONFIGURE for build jobs). Thus,
only one FreeBSD YAML template is defined instead and the Custom
executor scripts on FreeBSD runners extract the OS version to use from
the CI job name. This allows .gitlab-ci.yml variables to be defined for
FreeBSD jobs in the same way as for Docker-based jobs.

When kyua is called without the --logfile command line option, the log
file is created at a default location which is derived from the HOME
environment variable. On FreeBSD GitLab CI runners, /home is a
read-only directory and thus kyua invocations not using the --logfile
option fail when HOME is set to something beneath /home. Set --logfile
to /dev/null for all kyua invocations whose logs are irrelevant in order
to prevent kyua failures caused by HOME being non-writable.

For newer versions of Xcode, "xcode-select --install" no longer installs
system headers into /usr/include (instead, they are installed in the
Xcode directory tree), so do not mention that path in the macOS section
of README to prevent confusion.
