Hi all,

Thanks to intensive work by Martin Hurton, we have a new ZMTP/2.0 protocol spec.

It's here: http://rfc.zeromq.org/spec:15

The key things are (a) the protocol now has version numbering (yay!),
(b) it allows socket type verification and (c) it allows backwards
compatibility with 0MQ/2.2 apps.

All comments and criticisms welcome. This protocol is implemented in
the current libzmq master. When it's stable we'll cut the 3.2 stable
