[PATCH 2/3] Disable mouse events if the command window has focos

[Hannes Domani <ssbssa@yahoo.de>]

This is necessary because if the command window has focus, the keypad is
disabled, and without the keypad the mouse escape sequences are not handled
by curses, and instead seen by gdb as console input.

gdb/ChangeLog:

2021-06-07  Hannes Domani  <ssbssa@yahoo.de>

	* tui/tui-data.c (tui_set_win_focus_to): Add mousemask call.
	* tui/tui-io.c (tui_prep_terminal): Only call mousemask if
	command window doesn't have focus.
