I do not modify ip_pcbopt in any way.  All the IP Options stuff is simply
a 1:1 code move to get them all in one single place.

For ip_reass() I've taken a very conservative approach and just moved
the external code into the function itself.  In terms of coding style
it looks a bit ugly but is a pure 1:1 adaption of the existing code.
Thus I'm sure that I haven't changed the behaviour of the ip reassembly
code in any way (except one).  I agree that a rewrite of ip_reass() is
a very delicate thing because of possible bugs, but that is not what I
have done.
