FreeBSD user space support - First additions

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.
