[PATCH 25/66] Introduce the refresh_all method

[Tom Tromey <tom@tromey.com>]

This introduces the tui_win_info::refresh_all method and implements it
as needed in subclasses.  The name and comment are a bit of a guess on
my part.  The main benefit of this patch is removing another switch on
the type of the window.

gdb/ChangeLog
2019-06-23  Tom Tromey  <tom@tromey.com>

	* tui/tui.c (tui_rl_other_window): Call the refresh_all method.
	* tui/tui-windata.c (tui_data_window::refresh_all): Rename from
	tui_refresh_data_win.
	* tui/tui-win.c (tui_source_window_base::refresh_all): New
	method.
	(tui_refresh_all_win): Call the refresh_all method.
	(tui_set_focus): Likewise.
	* tui/tui-data.h (struct tui_win_info) <refresh_all>: New method.
	(struct tui_source_window_base, struct tui_data_window) <refresh>:
	Likewise.
