Fix race condition on shutdown

Removed over-long pauses in tests

- used msleep (10) in most places instead of zmq_sleep (1)
- may cause failures on slower machines
- to change, modify SETTLE_TIME in testutil.h
- tested down to 1 msec on fast boxes

zmq: change TIPC default lookup domain when connecting

By default, TIPC uses a closest first approach to find
a publication that can satisfy your connection request.
Any publication on the local node will automatically
be chosen for all requests, even if you're trying to
spread it out over multiple machines.
We fix this by widening the default lookup scope.

Fixed issue 578

Doc examples with zmq_msg_close usage - parameter is 'zmq_msg_t *'

Documentation examples for zmq_msg_get and zmq_msg_more functions have an
incorrect call to zmq_msg_close function - with 'zmq_msg_t' as a parameter
despite 'zmq_msg_t *' is required, so it is impossible to compile these
examples properly.

Also for zmq_msg_get example - declaration of zmq_msg_t variable is added
(like it is done in other examples).

zmq: narrow condition to include TIPC in build/test

As TIPC transport for 0MQ will only work on post 3.8
Linux kernels where nonblocking connect was added,
we add AC_RUN test to check for this functionality.
Should the test fail, tipc is excluded from build/test.

The tests are identical to the TCP ones, only the
addressing is changed.

A ZeroMQ application can opt for TIPC based sockets
using the TIPC port name format:
zmq_bind(sb, "tipc://{type,lower,upper}");
zmq_connect(sc, "tipc://{type,inst}");

'type' is the service ID, and 'lower/upper' can be
used for service partitioning or basic load
balancing.

ZeroMQ TIPC transport requires a kernel >= 3.8
(nonblocking connect support for TIPC).

Shorten ZMQ_ROUTER_REASSIGN_IDENTITIES to ZMQ_ROUTER_HANDOVER. Also, added a test for the HANDOVER functionality.

Fixed LIBZMQ-556: ROUTER socket does not support reconnection from clients with multiple NICs

Update tcp_connecter.cpp - Crash Fix: Assertion failed: Permission denied (..\..\..\src\tcp_connecter.cpp:279) on windows 8

Crash Fix: Assertion failed: Permission denied (..\..\..\src\tcp_connecter.cpp:279) on windows 8

Remove redundant entry in tests makefile.

Adding source for test_stream_empty

Sync cmake tests with tests in makefile.am

Renamed test_router_raw_empty to test_stream_empty

* The ZMQ_ROUTER_RAW API was deprecated in favor of ZMQ_STREAM
* Same issue hit router.cpp, which I've fixed

Fixed ref to zmq_socket_monitor
