All our MSVS Project files share the same intermediate directory. We
know that this doesn't cause any problems, so we can just disable the
detection in the project files.
Example of the warning:
warning MSB8028: The intermediate directory (.\Release\) contains files shared from another project (dnssectool.vcxproj). This can lead to incorrect clean and rebuild behavior.
(cherry picked from commit b6c2012d93)
Our vcxproj files set the WarningLevel to Level3, which is too verbose
for a code that needs to be portable. That basically leads to ignoring
all the errors that MSVC produces. This commits downgrades the
WarningLevel to Level1 and enables treating warnings as errors for
Release builds. For the Debug builds the WarningLevel got upgraded to
Level4, and treating warnings as errors is explicitly disabled.
We should eventually make the code clean of all MSVC warnings, but it's
a long way to go for Level4, so it's more reasonable to start at Level1.
For reference[1], these are the warning levels as described by MSVC
documentation:
* /W0 suppresses all warnings. It's equivalent to /w.
* /W1 displays level 1 (severe) warnings. /W1 is the default setting
in the command-line compiler.
* /W2 displays level 1 and level 2 (significant) warnings.
* /W3 displays level 1, level 2, and level 3 (production quality)
warnings. /W3 is the default setting in the IDE.
* /W4 displays level 1, level 2, and level 3 warnings, and all level 4
(informational) warnings that aren't off by default. We recommend
that you use this option to provide lint-like warnings. For a new
project, it may be best to use /W4 in all compilations. This option
helps ensure the fewest possible hard-to-find code defects.
* /Wall displays all warnings displayed by /W4 and all other warnings
that /W4 doesn't include — for example, warnings that are off by
default.
* /WX treats all compiler warnings as errors. For a new project, it
may be best to use /WX in all compilations; resolving all warnings
ensures the fewest possible hard-to-find code defects.

Windows BIND releases produced by GitLab CI are built from Git
repositories, not from release tarballs, which means the "srcid" file is
not present in the top source directory when MSBuild is invoked. This
causes the Git commit hash for such builds to be set to "unset_id".
Enable win32utils/Configure to try determining the commit hash for a
build by invoking Git on the build host if the "srcid" file is not
present (which is what its Unix counterpart does).

Our python code didn't adhere to any coding standard. In this commit, we add
flame8 (https://pypi.org/project/flake8/), and pylint (https://www.pylint.org/).
There's couple of exceptions:
- ans.py scripts are not checked, nor fixed as part of this MR
- pylint's missing-*-docstring and duplicate-code checks have
been disabled via .pylintrc
Both exceptions should be removed in due time.

This test asserts that option "deny-answer-aliases" works correctly
when forwarding requests.
As a matter of example, the behavior expected for a forwarder BIND
instance, having an option such as deny-answer-aliases { "domain"; }
is that when forwarding a request for *.anything-but-domain, it is
expected that it will return SERVFAIL if any answer received has a CNAME
for "*.domain".
BIND wasn't honoring option "deny-answer-aliases" when configured to
forward queries.
Before the fix it was possible for nameservers listed in "forwarders"
option to return CNAME answers pointing to unrelated domains of the
original query, which could be used as a vector for rebinding attacks.
The fix ensures that BIND apply filters even if configured as a forwarder
instance.
ORACLE MySQL 8.0 has dropped the my_bool type, so we need to reinstate
it back when compiling with that version or higher. MariaDB is still
keeping the my_bool type. The numbering between the two (MariaDB 5.x
jumped to MariaDB 10.x) doesn't make the life of the developer easy.

Most build/test job names already contain a "clang", "gcc", or "msvc"
prefix which indicates the compiler used for a given job. Apply that
naming convention to all build/test job names.

Multiple YAML keys have identical values for both TSAN unit test job
definitions. Extract these common keys to a YAML anchor and use it in
TSAN unit test job definitions to reduce code duplication.
(cherry picked from commit 84463f33bf)
Definitions of jobs running unit tests under TSAN contain an
"after_script" YAML key. Since the "unit_test_job" anchor is included
in those job definitions before "after_script" is defined, the
job-specific value of that key overrides the one defined in the included
anchor. This prevents "kyua report-html" from being run for TSAN unit
test jobs. Moving the invocation of "kyua report-html" to the "script"
key in the "unit_test_job" anchor is not acceptable as it would cause
the exit code of that command to determine the result of all unit test
jobs and we need that to be the exit code of "make unit". Instead, add
"kyua report-html" invocations to the "after_script" key of TSAN unit
test job definitions to address the problem without affecting other job
definitions.
(cherry picked from commit 6ebce9425e)
Multiple YAML keys have identical values for both TSAN system test job
definitions. Extract these common keys to a YAML anchor and use it in
TSAN system test job definitions to reduce code duplication.
(cherry picked from commit a9aa295f1f)
Both "system_test_job" and "unit_test_job" YAML anchors contain a
"before_script" key. TSAN job definitions first specify their own value
of the "before_script" key and then include the aforementioned YAML
anchors, which results in the value of the "before_script" key being
overridden with the value specified by the included anchor. Given this,
remove "before_script" definitions specific to TSAN jobs as they serve
no practical purpose.
(cherry picked from commit 8ef01c7b50)
All assignments for the TSAN_OPTIONS variable are identical across the
entire .gitlab-ci.yml file. Define a global TSAN_OPTIONS_COMMON
variable and use it in job definitions to reduce code duplication.

The custom builds (oot, asan, tsan) were mostly built using Debian sid
amd64 image. The problem was that this image broke too easily, because
it's Debian "unstable" after all.
This commit introduces "base_image" that should be most stable with
extra bits on top (clang, coccinelle, cppcheck, ...). Currently, that
would be Debian buster amd64.
Other changes introduced by this commit:
* Change the default clang version to 10
* Run both ASAN and TSAN with both gcc and clang compilers
* Remove Clang Debian stretch i386 job
