* passwd.c (UF_LOCKOUT): Remove (defined in lmaccess.h).

	(version): Bump version number to 1.5.
	(longopts): Add -c, -C, -e, -E, -p, -P options.
	(opts): Ditto.
	(PrintPW): Print values of UF_PASSWD_CANT_CHANGE and
	UF_DONT_EXPIRE_PASSWD flags. Slightly reformat output. Don't suppress
	correct system password settings just because the account has admin
	privileges.
	(usage): Define as "noreturn" function. Restructure and rephrase
	output. Accomodate new options.
	(print_version): Fix copyright dates.
	(main): Accomodate new options for setting UF_PASSWD_CANT_CHANGE,
	UF_DONT_EXPIRE_PASSWD and UF_PASSWD_NOTREQD settings.
