Awesome... could you push this as a pull request so we can play with
it. Please check https://github.com/zeromq/libzmq/issues/802 where we
were discussing this.

I'd like to be able to access all sender metadata for a message,
eventually, and allow clients to set metadata before connecting.

Breaking the zmq_msg_t structure is problematic, it means recompiling
applications as the size is defined in zmq.h.

Perhaps we could add a new type, zmq_frame_t, for this, and take the
opportunity to fix that msg/frame fuzziness.
