This means we don't need to distinguish between DBUS_NAME_TEST_EXEC and
DBUS_TEST_EXEC any more, because all test helper executables are in the
same place, both during build and when installed (we don't install
test-privserver since no installed test requires it yet, but in
principle we could).

We don't want to set these globally via the normal CFLAGS, because if
we did, AddressSanitizer would catch test-segfault deliberately
segfaulting, and "helpfully" turn it into exit status 1, which in turn
makes our test fail because it asserts that the segfault is reported
as a segfault.
A typical use with gcc as compiler, on a reasonably recent Debian,
would be:
./configure SANITIZE_CFLAGS="-fsanitize=address -fsanitize=undefined -fPIE -pie"

It's only used in test code. We have to put it in its own translation
unit with no non-libc dependencies so that we can compile a copy of it
without AddressSanitizer support, because in a subsequent commit we will
special-case test-segfault to be compiled without using AddressSanitizer,
which would make linking to an AddressSanitizer-instrumented libdbus fail.

Autotools creates executable applications in the respective
subdirectory of the build directory, while cmake creates
them in <build-root>/bin.
This leads to different paths in the file created
from org.freedesktop.DBus.TestSuite.PrivServer.service.in,
which are fixed by the new variable.

This simplifies bootstrapping: now you don't have to build dbus,
build dbus-python (with GLib), and use dbus-python to test dbus.
It also avoids test failures when using facilities like
AddressSanitizer. When libdbus is built with AddressSanitizer, but the
system copies of Python and dbus-python were not, dbus-python will exit
the Python interpreter on load, because libasan wasn't already
initialized. The simplest way to avoid this is to not use Python:
the scripts are not *that* hard to translate into C.
Both of these tests happen to be conditionally compiled for Unix only.
test_activation_forking() relies on code in TestSuiteForkingEchoService
that calls fork(), which can only work on Unix; meanwhile,
test_system_signals() tests the system bus configuration, which is
only relevant to Unix because we don't support using dbus-daemon as
a privilege boundary on Windows (and in any case D-Bus is not a Windows
OS feature, so the system bus cannot be used to communicate with OS
services like it can on most Linux systems).
This is also a partial solution to
<https://gitlab.freedesktop.org/dbus/dbus/issues/135>, by reducing the
size of name-test/.
For this to work, we need to build the test-service helper executable
even if embedded tests are disabled.

We might need these to run tests at build-time, so we should build them
whenever either modular or embedded tests are enabled, even if
installed-tests aren't.
We haven't noticed this bug until now because $(installable_helpers)
only contained test-apparmor-activation, which isn't normally needed at
build-time because the AppArmor test can only work when run as root.

These tests were disabled by commit 9c3d566, which rewrote the D-Bus
type system to be fully recursive, back in 2005. The message builder
was subsequently removed by commit 9d21554, also in early 2005.
It will probably take significant work to turn these files into
test-cases that use the current D-Bus type system and so can be run
this decade. Until that work is done, let's not ship them: we can
always fetch them from git history if we want them.
The single .message-raw file can still be read and has been retained,
although it hasn't actually tested the intended failure mode since
2005 due to changes to the D-Bus specification (it is a wire-protocol
version 0 message, and the recursive type system introduced in commit
9c3d566 changed the wire-protocol version to 1).

This lets cooperating processes with the same value of $HOME
interoperate for DBUS_COOKIE_SHA1 by reading and writing $HOME, even
if their $HOME differs from the uid's "official" home directory
according to getpwuid(). Out of paranoia, we only do this if the uid
and the euid are equal, since if they were unequal the correct thing
to do would be ambiguous.
In particular, Debian autobuilders run as a user whose "official"
home directory in /etc/passwd is "/nonexistent", as a mechanism to
detect non-deterministic build processes that rely on the contents of
the home directory. Until now, this meant we couldn't run dbus'
build-time tests, because every test that used DBUS_COOKIE_SHA1 would
fail in this environment.
In the tests, set HOME as well as DBUS_TEST_HOMEDIR. We keep
DBUS_TEST_HOMEDIR too, because Windows doesn't use HOME, only HOMEDRIVE
and HOMEPATH.

It is too easy for a developer working in an environment that has a
session bus to write tests that pass locally, but fail in minimal
environments. This is also risky because the tests might do
destructive things on the developer's real session bus. We can avoid
connecting to the session bus by consistently removing its address
from the environment, and replacing it with something that will
always fail.

At the moment there is a hack in the implementation of GetMachineId()
to stop tests from failing during "make check" on a system where
dbus has never been installed, by silently generating a new unique
fake "machine ID" for each process. I'm about to change that
behaviour to report errors properly; skip affected test-cases if we
can't read the real machine ID.
The shell scripts to test dbus-launch are run both as "make check"
tests (for which it is valid for dbus to be not correctly installed)
and as installed-tests (for which that is not valid), so make them
pass during "make check" but fail during installed testing.
The tests in bus/ and test/name-test/ are only run during "make check"
so they only have the code path where they are skipped.
