In an embedded system where the D-Bus session is a core part of the
environment, like Maemo, accidentally auto-launching a second session bus
(for instance for a concurrent ssh session) is a bad idea - it can lead
to a "split brain" situation where half the applications in the GUI are
using a different bus. In these controlled environments, it'd be useful
to prevent autolaunch from ever happening.
(As a side benefit, the changes to configure.in also mean that packagers
can explicitly --enable-x11-autolaunch, to make sure that failure to find
X will make compilation fail cleanly.)

Bug-NB: NB#219964
The code for accessing services requires absolute pathes, which are based
on DBUS_DATADIR. DBUS_DATADIR on windows is defined relative. This patch
makes sure that those pathes are absolute.
Libdbus uses several config variables. On unix these settings are read from
environment variables by using _dbus_getenv.
On other platforms like wince there are no environment variables available and
_dbus_getenv needs an emulation for those plattforms (see
dbus/dbus-sysdeps-wince-glue.c)
To cleanup this emulation the appended patch adds a config api by adding
_dbus_config_... functions.
Also having all client config related functions listed in one header file
provides a good overview about which config attributes are available.
The default implementation retrieves the config values from environment
variables. For other os this could be easily extended or replaced by.
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.
If there is a *.cmake test file available for
a related *.in file, take the *.cmake test file
instead of the *.in file as test file source.
Also added some messages.
This is performed by including the files from the client lib in the internal one
and by removing the linking to dbus-1 for targets using the internal library.
Renamed DBUS_LIBRARIES to DBUS_INTERNAL_LIBRARIES and moved to top level CMakeLists.txt.
Removed obsolate references of dbus-internal library.
Added DBUS_LIBRARIES definition which contains only the dbus library.
