Olivier Fourdan 4e82a751fb window: check for possible loop in transients
If a broken or naughty application tries set up its windows to create
a loop in the transient relationship, mutter will hang, looping forever
in meta_window_foreach_ancestor()

To avoid looping infinitely at various point in the code, check for a
possible loop when setting the transient relationship and deny the
request to set a window transient for another if that would create a
loop.
