+ fix a symbol conflict that made ncurses.c C/c menu not work with Solaris xpg4 curses. + add refresh() call to dots_mvcur.c, needed to use mvcur() with Solaris xpg4 curses after calling newterm(). + minor fixes for configure script from work on ncurses-examples and tin. + improve animation in test/xmas.c by adding a time-delay in blinkit(). + modify several test programs to reflect that ncurses honors existing signal handlers in initscr(), while other implementations do not. + modify bs.c to make it easier to quit. + change ncurses-examples to use attr_t vs chtype to follow X/Open documentation more closely since Solaris xpg4-curses uses different values for WA_xxx vs A_xxx that rely on attr_t being an unsigned short. Tru64 aka OSF1, HPUX, AIX did as ncurses does, equating the two sets.
