From c2803587b6f2533514e1cfa9793d0a448e9c2c85 Mon Sep 17 00:00:00 2001

Subject: Small refactor.  Move several utility functions from glX_XML.py to
 FilterGLAPISpecBase (in gl_XML.py).  When these functions are used to emit
 common #define lines, the will automatically be undefined in
 FilterGLAPISpecBase::printFooter if header_tag is set (i.e., the file is a
 header file).

These changes do not modify the generated code.
