Hi all,

This patch introduces ZMQ_ROUTER and ZMQ_DEALER socket type that haven't 
existed so far in 3.0 branch.

It also separates their implementation from ZMQ_XREQ and ZMQ_XREP, 
although the implementations are identical at the moment.

The idea is to preserve the existing functionality in ZMQ_ROUTER and 
ZMQ_DEALER sockets (see "Survey: use of 0MQ request reply" thread for 
different use cases) so that no applications will be broken, while at 
the same time improving simple request/reply model (dropping messages 
from dead clients, automatic resend, dropping duplicates etc.) in 
ZMQ_XREP and ZMQ_XREQ sockets.
