shutdown, umount: logging improvements
In bugreports about hangs during the late shutdown we are often missing important information - what were we trying to unmount/detach when it hung. Instead of printing what we successfully unmounted, print what we are going to unmount/detach. And add messages to mark the completion of categories (mount/swap/loop/DM).
