py-zmq: updated to 17.0.0

17.0.0
Add zmq.Socket.send_serialized() and zmq.Socket.recv_serialized() for \ 
sending/receiving messages with custom serialization.
Add zmq.Socket.copy_threshold and zmq.COPY_THRESHOLD. Messages smaller than this \ 
are always copied, regardless of copy=False, to avoid overhead of zero-copy \ 
bookkeeping on small messages.
Added visible deprecation warnings to bundled tornado IOLoop. Tornado eventloop \ 
integration shouldn’t be used without a proper tornado install since pyzmq 14.
Allow pyzmq asyncio/tornado integration to run without installing zmq_poll() \ 
implementation. The following methods and classes are deprecated and no longer \ 
required:
- zmq.eventloop.ioloop.install()
- zmq.eventloop.ioloop.IOLoop
- zmq.asyncio.install()
- zmq.asyncio.ZMQEventLoop
Set RPATH correctly when building on macOS.
Compatibility fixes with tornado 5.0.dev (may not be quite enough for 5.0 final, \ 
which is not yet released as of pyzmq 17).
Draft support for CLIENT-SERVER routing_id and group.
