[PATCH]: Fix tui refresh after background on Solaris

[Stephane Carrez <Stephane dot Carrez at worldnet dot fr>]

Hi!

On Solaris when the gdb-tui is restored from background, the screen is
refreshed correctly but the cursor is not put at the correct place.
It should be in the command window at the current readline cursor.
(no such pb on Linux, or with ncurses 5.x).

The following patch solves this by explicitly restoring the cursor 
after SIGCONT.  I've committed this patch.

	* tuiIO.c (tui_cont_sig): Update cursor position on the screen to
	leave it in the command window.
	(tui_redisplay_readline): Save cursor position to restore the
	cursor after we go back from background.
	* tuiData.h (TuiCommandInfo): Add start_line member.
