Hook up the RendererQuery for __DRI2_RENDERER_HAS_CONTEXT_PRIORITY to report the available DRM_I915_GEM_CONTEXT_SETPARAM options based on the the default context. The kernel will valid the request to change context, so we get an accurate reflection of available support (based on kernel version and privilege) and we should only have to do it once during screen setup -- although the SETPARAM should be fast, they are still an ioctl each.
