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.

Look for Khronos OpenGL spec files using pkg-config, rather than downloading them
Also add a --with-khronos-spec-dir=PATH configure option so XWin can be directed
where to find these files without using the khronos-spec-files package
XWin with AIGLX requires OpenGL spec files in order to generate wrapper code which:
(1) thunks from the glapi dispatch table which uses the default cdecl calling convention
to native GL functions using the stdcall calling convention.
(2) performs function address lookup for OpenGL 1.2+ functions, which are treated
as extensions and so not directly linkable.
v2: KHRONOS_SPEC_DIR is only valid when XWIN_GLX_WINDOWS is defined. Avoid 'make dist'
seeing invalid dependencies by only including rules using KHRONOS_SPEC_DIR if
XWIN_GLX_WINDOWS is defined

Tarballs include the downloaded gl spec files, which will end up in
$(srcdir). But, git-based builds will not have them at all and will
need to download them from opengl.org. They'll land in in the build
directory instead of $(srcdir), and so we need to allow them to be in
either place.
This change checks for the files in $(srcdir), linking them to . if
present. Otherwise, it downloads them from opengl.org.
A suggested better solution is to have Mesa install these files somewhere.
