These environment variables are used by GLib's g_test_build_filename()
and related convenience functions, which make it easier for unit tests
to find data files in a way that works for both build-time tests and
"as-installed" tests. During "as-installed" testing, both variables
will normally be unset, and GLib uses the directory containing the
executable. In most cases that results in the right thing happening, and
this will also be true for dbus, since we install the test executables
in ${libexecdir}/installed-tests, helper executables in the same place,
and test data in ${libexecdir}/installed-tests/data.

In debug builds with "embedded tests" enabled, these will automatically
be used as input for the message-internals test.
Some of the messages themselves are output from a fuzzer, others are
simplifications to include only one reason for lack of validity per
message.
I've included an annotated hex-dump for each message here, but the dbus
test suite doesn't currently know how to convert hex to binary, so I've
also committed the corresponding binary. See the comment at the top of
each hex-dump for how to create the binary version (which requires the
xxd tool shipped with vim).
It would be nice for the dbus test suite to be able to convert the
annotated hex-dump to binary, either at build-time with a Python script
or at runtime by loading the text file and decoding the hex, but I don't
want to block on that for dbus/dbus#413 and dbus/dbus#418.

FreeBSD 13.0 has reached EOL and it appears packages
are built against a newer baseline now, so we end up
with missing symbol errors:
ld-elf.so.1: /lib/libc.so.7: version FBSD_1.7 required by /usr/local/lib/libpython3.9.so.1.0 not found
It also appears that the fdpass test still fails on 13.1, so update the
condition to less than 14.0
I am trying to run cross-compiled tests in QEMU with the build directory
mounted via smbfs, and therefore creating the sockets in the CWD does not
work. Using DBUS_TEST_SOCKET_DIR (/tmp by default) allows me to run the
tests successfully.
Debug messages in a background thread can corrupt the machine-readable
TAP output, and in particular GWin32AppInfo emits debug messages from
a background thread when we link to libgio.

The /odd-limit/at test passes on 13.1 and 14.0 images, but fails on 13.1.
Debugging has not given me any useful hints why this may be the case, so
disable this test on 13.0 for now.
This allows us to drop the ci_test_fatal: "no" override which will ensure
that any FreeBSD regressions are caught.
This makes it possible for projects to incorporate D-Bus as a CMake sub-project in a larger CMake project.
Before this PR, doing so would result in many errors.
This is because CMAKE_SOURCE_DIR and CMAKE_BINARY_DIR would point to directories above the D-Bus project.
Using paths relative to the project directory, PROJECT_SOURCE_DIR and PROJECT_BINARY_DIR, corrects for this.
This is really three separate test-cases: one for traditional
activation as a direct child process of the dbus-daemon, and two for
traditional activation (successful and failing) via the setuid
dbus-daemon-launch-helper on Unix.
The ones where activation succeeds extremely slow, as a result of the
instrumentation for simulating malloc() failures combined with a large
number of memory operations, particularly when using AddressSanitizer.
Splitting up "OOM" tests like these has a disproportionately good impact
on the time they take, because the simulated malloc() failure
instrumentation repeats the entire test making the first malloc() fail,
then making the second malloc() fail, and so on. For allocation failures
in the second half of the test, this means we repeat the first half of
the test with no malloc() failures a very large number of times, which
is not a good use of time, because we already tested it successfully.
Even when not using the "OOM" instrumentation, splitting up these tests
lets them run in parallel, which is also a major time saving.
Needless to say, this speeds up testing considerably. On my modern but
unexceptional x86 laptop, in a typical debug build with Meson, the old
dispatch test took just over 21 minutes, which drops to about 40 seconds
each for the new normal-activation and helper-activation tests (and for
most of that time, they're running in parallel, so the wall-clock time
taken for the whole test suite is somewhere around a minute).
In a debug build with Meson, gcc and AddressSanitizer, the old dispatch
test takes longer than my patience will allow, and the new separate
tests take about 5-6 minutes each. Reduce their timeout accordingly, but
not as far as the default for slow tests (5 minutes) to allow some
headroom for AddressSanitizer or slower systems.
The failed-helper-activation test is almost instantaneous, and no longer
needs to be marked as slow.

In a Linux user namespace, it is possible that we are uid 0 but are
unable to switch to some other uid like DBUS_USER or DBUS_TEST_USER,
because the other uid is not "mapped" in the user namespace, resulting
in setuid() or setresuid() failing with EINVAL "Invalid argument".
For example, it's easy for this to happen when running under the
bubblewrap tool.
Try to drop privileges in a child process, and skip the test if we
are unable to do so.

With Meson 0.63.0, detailed output of TAP tests is not logged, and the
test deadlocks if the stderr pipe fills up. I'm hoping this will be fixed
before 0.63.1, but in the meantime we can work around it by falling back
to the 'exitcode' protocol: this means we lose machine-readable detailed
test results, but at least our tests pass.
See https://github.com/mesonbuild/meson/issues/10577 and
https://github.com/mesonbuild/meson/issues/10563 for details of the
Meson regression.

Group slow tests (those taking about a minute or more in one of the
configurations built on Gitlab-CI) into a new 'slow' suite, which can
be used with `meson test --no-suite=slow` to run just the faster tests.
They default to a 5 minute timeout (usually enough) unless overridden
(bus/dispatch.c can be *very* slow when OOM testing is enabled, and
gets a 30 minute timeout).
For the remaining tests, default to Meson's usual 30 second timeout,
but bump up the timeout a bit in some cases to have a safety margin
(my method was to take the slowest run on our Gitlab-CI, and make sure
we're allowing about 3 times that long).

DBUS_SESSION_BUS_LISTEN_ADDRESS is the same as in non-test files:
the test data distinguishes between DBUS_SESSION_BUS_LISTEN_ADDRESS,
the real session bus configuration, and TEST_LISTEN, the test-only
configuration.
DBUS_TEST_HOMEDIR and HOME should be in the build directory, not
the source directory.

If a helper executable is not, in itself, a test-case, then we should
not generate metadata that tells ginsttest-runner to run it as a
test-case.
Meanwhile, we were previously generating foo_with_config.test metadata
for tests that don't get installed; stop doing that.
We also need to distinguish between the abstract name of the test
(which usually does not start with test-), the name of the .test file
(which does start with test- for compiled executables), and the name
of the executable (which may include .exe as well). To make validation
against the Autotools build system as straightforward as possible,
generate exactly the same names as in Autotools. We can consider removing
the test- prefix later, if we remove the Autotools build system.

Some items listed in the tests array are helper executables rather
than actually being tests, and should not be run as a test at any time.
Those have {"test": false}. Expand this special case to the scripts
array for completeness (although currently, no scripts need this).
Meanwhile, some items listed in the scripts array are "as-installed"
integration tests which cannot safely be run at build-time, because
they make assertions about the state of the installed system.
Introduce {"build_time_test": false} for these, and expand this special
case to the tests array for completeness (although currently, no
compiled executables need this).
