Fix ip option processing for raw IP sockets.  This whole thing is a compromise
between ignoring options specified in the setsockopt call if IP_HDRINCL is set
(the UCB choice when VJ's code was brought in) vs allowing them (what everyone
else did, and what is assumed by programs everywhere...sigh).

Also perform some checking of the passed down packet to avoid running off
the end of a mbuf chain.
