gsdx-ogl: generate nearly all gl entries function pointers I used glcorearb.h as input file Code is limited to core gl + KHR/ARB extension GL1.X must be handled manually (need only 3 functions) I think the solution would be to migrate gl.h/glext.h to the single glcorearb.h.

gsdx-ogl: use only core debug extension There are 2 extensions GL_ARB_debug_output (promoted from amd extension) and GL_KHR_debug (the core extension, promoted from GL_ARB_debug_output) As we use the callback we could drop the manual query of errors. And save us the load of the GL_ARB_debug_output extension function pointer.

gsdx-ogl: use the standard openGL name Function pointer was mangled to avoid any collision. Nowadays all symbols are hidden so no risk of collision. Syntax is nicer beside it would allow to put back GLES3.2. I think it supports most of the used extension. glActiveTexture & glBlendColor are provided without symbol query.
