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".
This requires a full checkout of the FreeBSD 8.2 source code.
The checkout we have been using is missing at least the libc,
include, and sys directories. The script to copy files in is
crude.
This eventually needs to separate the manually written .h files
out and add the RTEMS specific network initialization support
with functionality to program the IP addresses and gateways as
the old stack did.
