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.

+#  Temporary hack of a script to get FreeBSD user space header
+#  files and network libc source code into this tree.
+#
+#  NOTE: libc and include are NOT in the FreeBSD checkout used for the
+#        USB and TCP/IP stacks. This has to be addressed.
+#
+#  This probably could be integrated into the main Python script.
+#  But so far, there are no real transformations needed and the
+#  script just performs two tasks:
+#
+#  + copies source files from FreeBSD libc and include files into this tree
+#  + generates "wrapper" header files for the public network .h files
