[jds-review] bugster 6706624 user processes do not exit on DTU reset.., .

[Niall Power]

These patches fix bugster CR  #6706624 (user processes do not exit on 
DTU reset.

gnome-session-2.22 only attempts to stop the dbus-daemon session daemon 
process after
gtk_main() inside the main loop. When the DTU is reset, the code after 
the gtk_main()
function is never reached so cleanup doesn't happen.
The fix is to register an atexit() function that checks and stops the 
dbus-daemon process
if necessary.

AtExit (void)
