Windows returns unhandled exceptions from a running child
by specific exit codes and not by signals as on UNIX.
Therefore we use DBUS_ERROR_SPAWN_CHILD_EXITED for propagating
unhandled exceptions to the parent too.

Unlike eavesdropping, the point of capture is when the message is

This is a special connection that is not allowed to send anything,
and loses all its well-known names.
In future commits, it will get a new set of match rules and the
ability to eavesdrop on messages before the rest of the bus daemon
has had a chance to process them.

There is a DBusList* member of BusTransaction named "connections", while
its getter function bus_transaction_get_connections() returns
context->connections which in fact is a BusConnections pointer, this is
quite confusing. Because this is what bus_context_get_connections()
returns.
This patch call out to bus_context_get_connections() directly and remove
the then unused bus_transaction_get_connections().

In Unix, the tests listened on both debug-pipe (which is a socketpair,
or a TCP emulation of socketpair on Windows) and a Unix socket.
In the Windows port, the tests were hard-coded to listen on a particular
port, which allowed the dispatch test to connect to that port, as long
as no two tests ran simultaneously (which I don't think was ever guaranteed -
make -j can violate this). That's valid out-of-process, and also
fully-specified, so they only needed one <listen> directive, so the
CMake input only had one.
To make the tests work under CMake on Unix, there was a hack: the string
substituted for the content of the <listen> directive contained
</listen><listen> to get the other address in, which is pretty nasty.
Instead of doing that, I've made both build systems, on both Unix and
Windows, use both debug-pipe and a more normal transport (Unix or TCP).
debug-pipe has a Windows implementation and it's used in
dbus-spawn-win.c, so it'd better work. The use of debug-pipe is now
hard-coded rather than being a configure parameter (there's no reason
to vary it in different builds), and I used TEST_LISTEN as the name of the
Unix/TCP address, because it's a "vague" address (no specific Unix path, no
TCP port), that you can listen on but not connect to.
This in turn means that we can merge the Autoconf .in and CMake .cmake
files, similar to Bug #41033.
You might wonder why I've kept debug-pipe. I did try to get rid of it, but
it turns out that the tests in dispatch.c rely on
dbus_connection_open_private() not blocking, and normal socket
connections block on connect(). Until we fix that by adding an async
version of dbus_connection_open_private(), it won't be safe to have a
test like dispatch.c that "talks to itself", unless it uses a transport
as trivial as debug-pipe in which neither end has to block on the other.

Bug: https://bugs.freedesktop.org/show_bug.cgi?id=41222
Recent test configuration files contains 'unix:...'
bus adresses which do not work on windows.
For cross plattform usable test files the whole
listen tag entry has to be set by the build system,
which is available with a new build system variable
named TEST_LISTEN.
To have the client client side definition in sync,
TEST_CONNECTION has been moved from c file into cmake
build system.
This simply verifies that we forward unix fds only on connection that
support it. We willr eturn an error if a client attempts to send a
message with unix fds to another client that cannot do it.
This adds two new directives to the auth protocol:
NEGOTIATE_UNIX_FD is sent by the client after the authentication was
sucessful, i.e. OK was received.
AGREE_UNIX_FD is then sent by the server if it can do unix fd passing as
well.
ERROR is returned when the server cannot or is unwilling to do unix fd
passing.
This should be compatible with existing D-Bus implementations which will
naturally return ERROR on NEGOTIATE_UNIX_FD.

* bus/dispatch.c (bus_dispatch_test_conf): remove the "if

we didn't pass through all the expected errors from the helper.
* bus/activation-exit-codes.h
(BUS_SPAWN_EXIT_CODE_CHILD_SIGNALED): add a code for child segfaulting
(BUS_SPAWN_EXIT_CODE_GENERIC_FAILURE): make "1" be a generic

could just always return 1 on failure.
* configure.in: add AM_PROG_CC_C_O to allow per-target CPPFLAGS
* bus/dispatch.c (bus_dispatch_test_conf): Fix up setting
TEST_LAUNCH_HELPER_CONFIG to include the full path, and enable
test shell_fail_service_auto_start when use_launcher==TRUE
* bus/activation-helper-bin.c (convert_error_to_exit_code): pass
through the INVALID_ARGS error so the test suite works
* bus/activation.c (handle_activation_exit_error): return
DBUS_ERROR_NO_MEMORY if we get BUS_SPAWN_EXIT_CODE_NO_MEMORY
* dbus/dbus-spawn.c (_dbus_babysitter_get_child_exit_status):

exited normally (with a status code)

Move the call to notify dbus-bus.c into
