[PATCH 18/24] Remove tui_set_win_focus_to

[Tom Tromey <tom at tromey dot com>]

I noticed that the TUI had two functions with similar names:
tui_set_win_focus_to and tui_set_win_with_focus.

However, the former was just an implementation detail of the latter.
So, this patch removes the former entirely, to avoid any temptation to
call it.

2020-01-04  Tom Tromey  <tom@tromey.com>

	* tui/tui-win.c (tui_set_win_focus_to): Move to tui-data.c.
	* tui/tui-data.h (tui_set_win_with_focus): Don't declare.
	* tui/tui-data.c (tui_set_win_with_focus): Remove.
	(tui_set_win_focus_to): Move from tui-win.c.
