We need to change the yy template file used to generate the parser, if future
regenerations are to build automatically under Windows without further changes.

Specifically what's needed is:-

 - Don't include FreeBSD's <sys/cdefs.h> on non-FreeBSD platforms.

   [This is where the __unused definition originally came from; it's
   been manually hacked in in certain revisions of these generated files
   in Perforce history]

   ...which has been dealt with by this commit. Thanks!

 - Defines for fileno() and isatty() to use the underscore-prefixed
   versions of those routines in the Microsoft Visual C++ Runtime.

   [We compile with -D_NO_OLDNAMES in order to catch possibly erroneous
   or non-portable use of certain UNIX C library functions on Windows.
   The errors thus generated are useful to people trying to hack XORP
   on platforms which the core project doesn't currently support.]

 - Embrace #include "config.h" with #ifdef HAVE_CONFIG_H

   [Future proofing against other ways of building XORP failing if
   we ditch autotools, e.g. Jam/OS X ProjectBuilder, pmake, etc., i.e.
   if we build in a configuration with no config.h. ]
