  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.
