* fix wrong interaction when both GL41 or GL42 aren't supported
* Add a new define to downgrade opengl requirement to test the free driver and EGL
=> As far as I can tell, they only miss geometry shader& GLSL150 (got GLSL140)
* Found a way to avoid crash in AMD driver. Skip the upload of small texture but rendering is wrong now...

* replace both DISABLE_GL41_SSO and DISABLE_GL42 macro with a dynamic check based on the extension support
* glsl2h: use static instead of extern

* implement GSWndEGL copy/pasted from zzogl.
* remove linux debugging shader that failed to compile on window
* add additional debug message during context creation

* Remove bad redefinition of glActiveTexture and glBlendColor pointer
* Remove glew dependency on linux
* s/OGL_DEBUG/ENABLE_OGL_DEBUG/ and enable it on debug

* move GL loading function into its own namespace
* Use manual GL loading on linux too and mostly drop glew dependency. (Not 100% clean we are still depends on some glew define, it will be fixed later)
Note: shaders still need to be copied manually from GSdx/res to bin/plugins
