[PATCH]: Fix gdb window size when entering/leaving TUI mode

[Stephane Carrez <stcarrez at nerim dot fr>]

Hi!

When we enter/leave TUI mode the gdb's lines_per_page is not changed.
This patch fixes that by telling gdb what is the new width/height
of windows when we enter/leave TUI mode.

Committed on mainline.

2002-08-24  Stephane Carrez  <stcarrez@nerim.fr>

	* tuiWin.c (tui_update_gdb_sizes): New function to tell gdb what
	is the size of command window.
	(tuiResizeAll): Call it instead of init_page_info.
	* tui.c (tui_enable): Call it to resize to TUI command window.
	(tui_disable): Likewise for plain screen.
