Author: Tom Tromey <tom@tromey.com>
Date:   Sat Sep 24 21:53:54 2016 -0600

    Remove make_cleanup_restore_current_uiout
    
    This removes make_cleanup_restore_current_uiout in favor of an
    RAII-based class.
    
    2016-10-21  Tom Tromey  <tom@tromey.com>
    
    	* stack.c (print_stack_frame_to_uiout): Use scoped_restore.
    	* ui-out.c (make_cleanup_restore_current_uiout)
    	(restore_current_uiout_cleanup): Remove.
    	* infrun.c (print_stop_event): Use scoped_restore.
    	* ui-out.h (make_cleanup_restore_current_uiout): Don't declare.
