Added assert on duplicate id in ROUTER and STREAM sockets.  Updated man to reflect this change.  Modified test case to match.

Cleaned up formatting of test_connect_rid.  Set LINGER to 0 on sockets.  This may address the test failing on some devices.

Fix compilation of tests on MSVC 2008

ZMQ_CONNECT_RID tests and man

Updated man entries, and added behavior in case the user duplicates peer ids.  In this case the socket reverts to default behavior.

Cleaned up option to force identity on outgoing connection

- renamed to ZMQ_CONNECT_RID
- fixed whitespace malformating around previous patch
- renamamed next_peer_id to next_rid in preparation for
  larger rename of IDENTITY to ROUTING_ID

Note: ZMQ_CONNECT_RID has no test case and no entry in the man
page, as yet.

Fixed compile issue with missing member of socket_base.  Changed ZMQ_NEX...

Fix cmake build and warnings

Fixed compile issue with missing member of socket_base.  Changed ZMQ_NEXT_IDENTITY to ZMQ_NEXT_CONNECT_PEER_ID.

Fixed case where ZMQ_NEXT_CONNECT_PEER_ID is used in ROUTER, and ROUTER does not read the identity message from the connected pipe.

Updated STREAM and ROUTER sockets to allow for pre-naming of outbound connections

Store socket FD after connect

Add STREAM connect notification.

Both STREAM and ROUTER sockets suffer from a naming problem on outbound connections. While these connections can be created, they can't be immediately used. Traffic must be received before it can be sent. This prevents practical, minimal usage of STREAM or ROUTER as a true N fan in/out socket.

This change simply provides the user with a socket option that sets a user defined name of the next outbound connection:

zmq_setsockopt(routerSock,ZMQ_NEXT_IDENTITY,"myname",6);
if(0 > zmq_connect(routerSock,"tcp://127.0.0.1:1234")) return 1;
ret = zmq_send(routerSock,"myname",6,ZMQ_SNDMORE);
zmq_send(routerSock,b.mem,b.used,0);

In this example, the socket is immediately given the name "myname", and is capable of immediately sending traffic.

This approach is more effective in three ways:
1) It prevents all sorts of malicious peer naming attacks that can cause undefined behavior in existing ROUTER connections. (Two connections are made that both transmit the same name to the ROUTER, the ROUTER behavior is undefined)
2) It allows immediate control of connections made to external parties for STREAM sockets. Something that is not possible right now. Before an outbound connection had no name for STREAM or ROUTER sockets because outbound connections cannot be sent to without first receiving traffic.
3) It is simpler and more general than expecting two ROUTER sockets to handshake on assigned connection names. Plus it allows inline sending to new connections on ROUTER.

Adjust test cases to connection notification.
Increase error checking in test cases.

fixed cmake merge related to version.rc.in handling

Corrects ypipe initialization when conflate is NOT enabled.

Fixes LIBZMQ-584

Adds support for detecting ZMQ_STREAM disconnections.

Fixes CMake build after ZAP test file was deleted.

File was removed in 5bf96f64 a few days ago.

When a ZMQ_STREAM socket connection is broken (intentionally, via `shutdown()`
or accidentally via client crash or network failure), there is no way for the
application to dertermine that it should drop per-connection data (such as
buffers).

This contribution makes sure the application receives a 0-length message to
notify it that the connection has been broken.  This is symmetric with the
process of closing the connection from within the application (where the
application sends a 0-length message to tell ZeroMQ to close the connection).
