Fix compatibility with nginx-1.2.8+.

Update to ZeroMQ-3.2+.

This module was originally developed against ZeroMQ-2.x, but there
were many incompatible API changes introduced with ZeroMQ-3.x.

Some of those changes completely broke this module, e.g. data types
of a few ZeroMQ socket options were changed to types with different
sizes.

ZeroMQ-2.x is no longer supported.
