ipfw, status report

[marta carbone]

Hello,

I've started moving ipfw and dummynet code in a separate directory
and to split kernel related data structure in separate headers.
Since this part of the work was done in coordination with my mentor,
changes to the code are in the Luigi's svn branch.
Luigi is merging to HEAD the parts that are settled.

Next I am going to continue with the splitting of headers between
userland- and kernel- parts.
