Introduce strtonum(), which works like string_to_number(), but passes

back the 'end' pointer. It is useful where you want to do boundary
checking yet work with strings that are not entirely slurped by
strtoul(), e.g.:

	s = "1/2"; /* one half */
	if (!strtonum(s, &end, &value, 0, 5))
		error("Zero-length string, or value out of bounds");
	if (*end != '/')
		error("Malformed string");
	info->param1 = value;
	if (!strtonum(end + 1, &end, &value, 2, 4))
		error("..");
	if (*end != '\0')
		error("Malformed string");
	info->param2 = value;
