egl: support creating OpenGL contexts

Browse Source 
Right before we create the EGL context, we check if we were built with
OpenGL or OpenGLES support and it was OpenGL then we call eglBindAPI
(EGL_OPENGL_API); This also explicitly requests a EGL_RENDERABLE_TYPE
supporting the EGL_OPENGL_BIT.

This will let us add a new ./configure flavour that combines OpenGL and
EGL instead of OpenGL and GLX.
