Previously, the CMake build enabled tests by default, and enabled both
modular and intrusive (embedded) tests with a single option. This is
a really bad idea if anyone is using CMake-built binaries in production.
DBUS_BUILD_TESTS now enables only the modular tests, which are safe to
enable in production builds.
A new DBUS_ENABLE_INTRUSIVE_TESTS option enables the intrusive test
instrumentation.
To preserve existing test coverage, explicitly enable the intrusive
tests in most CMake-based Gitlab-CI jobs (Debian native, openSUSE native,
Windows).
In jobs that have a mirrored pair of production/debug builds (openSUSE
and Debian mingw32/mingw64 cmake), instead we leave the production
build as-is and only build full test coverage in the debug build.

With the minimum version set to 3.4, none of the policies need to be set explicitly to the `NEW` behavior.
Each of the policies removed here was introduced before CMake version 3.4.
By default then, each of them will be set to NEW automatically.
This is part of the behavior of cmake_minimum_required.
The cmake_policy commands are therefore redundant and have been removed.
Inferring it from the environment is not correct, since the host system
could have a different temporary directory defined. Instead of guessing
based on the host, require the user to pass an explicit directory when
cross-compiling. This is helpful for me since I am cross-compiling for
FreeBSD from macOS and on my host TMPDIR is set to
/var/folders/<random characters>/T/ instead of the expected /tmp.
We've had a request for a 1.14.x stable-branch, but the Containers
interface is only partially implemented, not yet described in the
D-Bus Specification, and not ready to be part of our API guarantees.

Checking the filenames of generated configuration files is now optionally
possible with this cmake option. They are no longer displayed by default
to avoid unnecessarily flooding the output.
Systemd user support is controlled by the cmake variable ENABLE_USER_SESSION,
which and WITH_SYSTEMD_USERUNITDIR to specify a custom installation
location. If WITH_SYSTEMD_USERUNITDIR is not specified, the related install
path is determined from an installed systemd package, if present.
This was added to the Autotools build system as part of fd.o#61301,
but until now was not possible to enable when building with CMake.
Previously, only the Autotools build system could do this. This commit
includes most of the same features as in the Autotools build, although
not the user-session semantics, which will be added separately.
Systemd support is controlled by the cmake variable ENABLE_SYSTEMD, which can
have the values OFF, ON and AUTO, the latter enabling support by default if
the required libraries are available.
With WITH_SYSTEMD_SYSTEMUNITDIR a custom installation location can be specified.
If it is not specified, the related install path is determined from the installed
systemd package, if present.
Qt help files are used by Qt Creator and KDevelop, for example, to support
the development of Qt-based applications and libraries.
Generating api documentation in Qt help format is controlled by two
user specific options named --enable-qt-help and --with-qchdir (autotools)
and -DENABLE_QT_HELP and -DINSTALL_QCH_DIR (cmake).
If this variable is set, ctest uses wine to run cross compiled
test applications. Otherwise, they are assumed to run on a native
Windows operating system.
The new cmake variables Z_DRIVE_IF_WINE and TEST_WRAPPER have been
added to support this function.
The _Must_inspect_result_ annotation is documented to be used in both
the declaration and implementation, but in testing with the MSVC 2012
compiler it appears to be sufficient to use the annotation only in the
declaration to get a compiler warning, as with the GCC compiler.
So the annotation is not necessary in the C implementation.

This is nicer for cross-compiling, because AC_RUN_IFELSE can't work
there. In practice abstract sockets are supported on Linux since
2.2 (so, all relevant versions), and on no other platform; so it
seems futile to keep this complexity.

With this support cmake and autotools generates cmake equivalent of
pkgconfig files on configure time named DBus1Config*.cmake. These
files are installed into the related directory where cmake expects
find_package related config files.
For instructions how to use this feature with clients see readme.cmake.
With previous DBus versions each cmake client using DBus as dependency
needed a related FindDBus*.cmake in its source distribution or in
the cmake binary packages. With the 'config' find package style support
provided by this patch this requirement has been removed.
The generated config file uses pkgconfig on unix or autotools to
fetch package build flags, which is the prefered way. On Windows
we do not want to require CMake users to have pkg-config installed
so it uses cmake buildin target export support for exporting all
targets into DBus1ConfigTargets*.cmake.

On Unix, the connect address should basically always be "autolaunch:"
but the listen address has to be something you can listen on.
On Windows, you can listen on "autolaunch:" or
"autolaunch:scope=*install-path", for instance, and the dbus-daemon is
involved in the auto-launching process.

The system bus is unsupported (and rather meaningless) on Windows anyway,
so we can use anything. Also, make it clear that it has to be a
"specific" address that can be listened on *and* connected to,
like unix:path=/xxx - a listen-only address like unix:tmpdir=/xxx or
nonce-tcp: would not be suitable.
