  Add an auto-generated dispatch table for GL bindings.
  
  This will more easily allow us to extend our implementation to make a
  NULL or "stub" set of bindings. It also exposes a lot more function
  permutations via extension variations.
  
  It might improve the loading speed for bindings obtained via
  extensions. Instead of generating a list every time an extension is
  checked, we use a single std::set for a fast query. However because
  more extensions are checked for more entry points, it might not make
  a huge difference.
  
  This also fixes an issue where the "real" ANGLE GL headers were being
  propagated to the entry point dispatch table definitions, instead of
  being in a totally isolated file. This patch adds the missing typedefs
  to our proxy headers.
  
  It also fixes the naming of a few entry points which was inconsistent
  with the spec. It also makes an XML adjustment to GL_NV_path_rendering
  to accomodate a hole in the spec where glLoadMatrixfEXT was not ever
  defined in OpenGL ES. A spec oddity with the TexStorage extension is
  not resolved - in this case, some methods are only exposed if other
  extensions are present, but this information is missing from gl.xml.
