[rfa/tui] Include <ncurses.h> when available.

[Andrew Cagney <ac131313 at cygnus dot com>]

Hello,

The attatched twiddles gdb/tui so that it will include <ncurses.h> when
available.  I've found <ncurses.h> to be more complete than <curses.h>
on some systems.  The patch also eliminates a few stray <curses.h>
includes.

For those that are wondering, yes, this patch has the potential to clash
with utils.c:#include<curses.h> ("tui.h" can be included by defs.h). 
Since the TUI is still HP only that doesn't occure in the field.  Longer
term I hope to see defs.h:#include<tui.h> replaced.

	ok?
