net-setup: Add routing and old stack's configuration

Browse Source 
This allows the old stack's configuration structures to be used
unchanged even though this code currently does not support all
of the options. It likely will never support all of the options
as some should eventually come through configuration files as
they would in a real FreeBSD system. Other configuration
parameters are likely configurable via "hints".
