Subject: * dbus/dbus-sysdeps-unix.c: moved _dbus_atomic_inc/dec() from
 dbus/dbus-sysdeps.c, windows version of _dbus_atomic_inc/dec() is in
 dbus-sysdeps-win.c (not in this patch).

* dbus/dbus-sysdeps.h: DBusAtomic::value is long on windows to fit
with InterlockedInc/Decrement. - Patches from Christian Ehrlicher
