The same code detecting the session config path and debug/release 
version of dbus-daemon is required in the dbus-daemon.

The autolaunch feature see _dbus_get_autolaunch_address() in 
dbus/dbus-sysdeps-win.c uses the --session parameter to run the dbus-daemon.

The dbus-daemon currently uses a hardcoded path 'etc/session.conf', 
which only works if dbus-daemon is installed [1] and the working dir of 
dbus-daemon is set to the dbus installation root and the path layout is 
like shown below

<dbus-install-root>/
    bin/dbus-daemon.exe
    etc/session.conf

If dbus-daemon is running in the build environment the path layout looks 
different

<dbus-build-root>/
    bin/dbus-daemon.exe
    bus/session.conf


The solution for this problem is to implement the session.conf search in 
bus/main.c where the config_file parameter is set and to use the 
--session parameter in dbus-launch to start dbus-daemon.exe. This would 
fix also the limitation mentioned in [1]
