v1: Rewrite by Marc Haesen of the WGL wrapper function generation script to use
Khronos group XML.
v2: Remove -dispatchheader option, since dispatch.h doesn't exist anymore, use
the private glapi interface to construct the GL dispatch table for the native
WGL thunks.
v3:
Rewrite to generate shims for the OpenGL 1.2.1 (GL 1.2 + GL_ARB_imaging
+GL_ARB_multitexture + GL_ARB_texture_compression(?)) functions the server links
directly with rather than libGL.
These shims dispatch to either the mesa GL DLL, or a thunking DLL containing
cdecl-to-stcall wrapper functions for the native GL DLL.

Fix some of the warnings in generated gl wrapper code:
- glWinResolveHelper takes a const char * argument
- ensure formal parameter names don't collide with reserved names or shadow
global declarations (e.g. near, far, index (from string.h), remainder (from
math.h), pointer (from Xdefs.h) by postpending a '_'.

Create a new dispatch table rather than modifying the existing one
struct _glapi_table is not a complete type after including glapi.h, so we use
glapi_get_dispatch_table_size() to determine it's size (alternatively, we could
include glapitable.h, to complete the type)
This could possibly be written to use _glapi_create_table_from_handle() instead, but
that requires making all the wrapper functions exports
