[ros-diffs] [arty] 19110: Preliminary commit for tcpip control panel. I've been sitting on this

Preliminary commit for tcpip control panel.  I've been sitting on this 
for a while, mainly because it used to bugcheck in a named pipe call.
I've lost my modifications to dhcpcapi, so stuff in there might not
be right.  Looking at it.
