Gudmundur Adalsteinsson 47969cfdcf Problem: shutdown() missing for context_t (#377)
Solution: Add shutdown(). This function is required
for clean termination of the zmq context in multi-threaded
applications where sockets are used in threads. In particular
if blocking operation are used and if sockets can be created
at any time.

* Improve tests and documentation
