gsdx egl: rewrite the EGL implementation
Split code in 2 parts * Base class (GSWndEGL) that implement the core EGL and GL context * Derived class (GSWndEGL_X11/GSWndEGL_WL) that implement the backend to handle native resources Note: Most backend code is only useful for GSopen1/PS1 mode. GSopen2 only requires the AttachNativeWindow implementation Code is based around EGL_EXT_platform extension that allow to select the platform at runtime. Note: I think the extension was integrated in EGL 1.5 The X11 backend was mostly converted to XCB The wayland backend is only a placeholder for future code I don't know if MS windows is/could be supported with EGL_EXT_platform API Code validated on Mesa. Proprietary drivers aren't yet tested.
