	* frame.c (get_selected_frame): Add and use message parameter.
	* stack.c (current_frame_command, return_command, locals_info)
	(catch_info, args_info, up_silently_base, down_silently_base): Use
	get_selected_frame with an explicit message.
	* thread.c, stack.c, sh-tdep.c, sh64-tdep.c: Update.
	* remote-rdp.c, remote-mips.c, remote-e7000.c: Update.
