[ros-kernel] iphlpapi status

[art yerkes]

Our iphlpapi can now add and delete routes as well as provide information.  
I think this would be a good time put adding and deleteing routes in
our tcpip.sys

Currently, our iphlpapi works fine with win2k route.exe.  I'm going to
port busybox route as soon as I get to it, so that we have something
of our own.

The part that reads routes should be fairly self-explanatory, and is 
almost documented.  The writing part is not.  Attached are some notes
I took while finding out how it works.

The only other thing to know is that the route manipulation functions
are in the new file lib/iphlpapi/route_reactos.c
