Provide OpenGL over Egl The Egl backend is decoupled from the OpenGL ES build option which makes it possible to use it as a replacement for glx. To make this possible a new build flag is added when egl is available at compile time and any egl specific code is now ifdefed with this flag instead of the gles flag. In addition at runtime a windowing system enum value is passed to the various detect methods to have egl/glx specific detection for e.g. function pointer resolving. By default egl is used if compiled with OpenGL ES, otherwise glx is used. But in the non-gles case the windowing system can be selected through the new environment variable KWIN_OPENGL_INTERFACE. Setting this variable to "egl" the EglOnXBackend is used. REVIEW: 106632

Use libepoxy to resolve GL functions Remove the manually written GL dispatch code, and use libepoxy to resolve functions. The only exceptions are GLX_MESA_swap_control, which is not in the XML API registry, and GL_ARB_robustness/GL_EXT_robustness. For the latter we want to resolve the functions to the same names on both GLES and desktop GL, and plug in our own implementations when the extension is not supported.

Handle conflicts between epoxy and manually resolved function pointers For the functions from GL_FOO_robustness we want to resolve it by ourselves in order to add a custom implementation if it's not available. Unfortunately once epoxy.h is included this breaks as epoxy defines the names and so through the preprocessor epoxy always wins. So we need different names: all functions from robustness get a "kwin" prefix and the usage is changed everywhere in kwin source code. REVIEW: 125883
