- Implement nanomsg multipart with MessagePack. - Use the MessagePack from FairSoft and handle not found case. - Update splitter, merger and proxy devices to handle multi-part. - Let FairMQParts.At() return pointer reference (can be used for moving). - Add missing const specifier in the message interface. - Add transmit kernel size setting to channels (ZMQ_SNDBUF). - Remove FairMQBuffer device. - Remove old multi-part methods from Tutorial3 example (to be replaced with Parts API). - Make callback mandatory for newMsg(data, size, callback). - Add missing <vector> include in FairMQSocket.
