accept NUL-terminated strings as required by RFC 2132.
This solution is not perfect as it removes the ability to send
NUL-terminated host-name options which may be required by some broken
servers. Given the current lack of an existance proof of such servers
and the fact that servers that send NUL-terminated domain names do
exist, this seems like an acceptable compromise. A discussion of these
issues can be found at:
