list_window: remove list_window_state_t

We do not need to save a stack of list window states.  When we return
to a parent directory, we just have to find the directory which we
come from in the parent list.  Note that this patch resets the cursor
when going to the root directory, but I think it's not that important,
and I will deal with that later.
