Return int, not void, to conform with the expected arg of tputs. * readline.c (init_terminal_io): tgetflag only takes 1 arg. * readline.c (_rl_savestring): New function. * chardefs.h: To avoid conflicts and/or warnings, define savestring as a macro wrapper for _rl_savestring. * display.c (extern term_xn): It's an int flag, not a string. * charsdefs.h, rldefs.h: Remove HAVE_STRING_H-related junk.
