Rainer Orth 6e7e1744e9 Fix tui compilation with Solaris libcurses: clear define (PR tui/21482)
On both mainline and the 8.0 branch, gdb compilation fails on Solaris 10
with the native libcurses like this:

It turned out this happens because <curses.h> has

#define clear()         wclear(stdscr)

This can be avoided by defining NOMACROS, which the patch below does.
ncurses potentially has a similar problem, which can be avoided by defining
NCURSES_NOMACROS.

	PR tui/21482
	* gdb_curses.h (NOMACROS): Define.
	(NCURSES_NOMACROS): Define.
