The Py_REF_DEBUG/COUNT_ALLOCS/Py_TRACE_REFS macro minefield: added

more trivial lexical helper macros so that uses of these guys expand
to nothing at all when they're not enabled.  This should help sub-
standard compilers that can't do a good job of optimizing away the
previous "(void)0" expressions.

Py_DECREF:  There's only one definition of this now.  Yay!  That
was that last one in the family defined multiple times in an #ifdef
maze.

Py_FatalError():  Changed the char* signature to const char*.

_Py_NegativeRefcount():  New helper function for the Py_REF_DEBUG
expansion of Py_DECREF.  Calling an external function cuts down on
the volume of generated code.  The previous inline expansion of abort()
didn't work as intended on Windows (the program often kept going, and
the error msg scrolled off the screen unseen).  _Py_NegativeRefcount
calls Py_FatalError instead, which captures our best knowledge of
how to abort effectively across platforms.

+- Py_FatalError() is now declared as taking a const char* argument.  It
+  was previously declared without const.  This should not affect working
+  code.

 - Added new macro PySequence_ITEM(o, i) that directly calls
   sq_item without rechecking that o is a sequence and without
   adjusting for negative indices.
