DHCP option parsing bug

Subject: DHCP option parsing bug

The attached patch fixes the DHCP option parsing to deal with DHCP servers that don't terminate their options with an END tag. The eCos implementation relies heavily on this. RFC 2132 doesn't specify if this END tag is required or not. Up until now, I have never seen a DHCP server do this, but have run into now.

There are other ways to implement this, but I chose this approach as the least invasive.
