Message : Add initial support for various stream extensions. Add entry points and validation for various egl stream extensions including EGL_KHR_stream_consumer_gltexture and EGL_NV_stream_consumer_gltexture_yuv and NV_EGL_stream_consumer_external. The extensions functionality is not yet implemented and the extension strings are thus not exposed yet.
