This implements initial support for GL_EXT_external_objects. An external memory object is (unlike EGL images) represented by a GLuint just like all other GL objects. It needs to be kept alive for as long as the memory is used, which means it needs to outlive the texture ID. That's why the object is handed over to the texture code and the finalizer will then free the memory object. This is just plumbing, users will follow in future commits.
