Enable all sorts of useful security features:

o XDM-AUTHORIZATION-1 is more automated for the non-USA case.
o PST's KerberosIV patches are reinstated for XDM. This is NOT
  a full-blown KerberosIV implementation for X - this will
  just get you a TGT when you log in - THATS ALL!
o Enable compilation of SecureRPC. The use of SecureRPC at the
  moment is frought with danger! I have no idea how safe or
  good the implementation is. Enable at your own peril!! (Secure
  RPC is only available for those folk using 3.0-Current).

Also allow XF86Setup to use TK-8.0.
