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.

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.

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).

- removed unnecessary malloc
- spaces, not tabs to indent
- renamed control states to be more logical
- renamed SUSPEND to PAUSE, feels more accurate
- fixed indentation, which was off in places
Abstract socket pathnames must have a NULL character in the first
position, but the second character must also be checked to differentiate
an abstract name from the empty string. The address length must also
indicate the length of the pathname because the kernel uses the entire
address as the name, including NULL characters. ZMQ uses
NULL-terminated strings for the address, so the abstract address length
is the length of the string following the initial NULL byte plus 3; two
bytes for the address family and one for the initial NULL character.
Converts an initial strudel or "at sign" (@) in the Unix socket path to
a NULL character ('\0') indicating that the socket uses the abstract
namespace instead of the filesystem namespace. For instance, binding a
socket to 'ipc://@/tmp/tester' will not create a file associated with
the socket whereas binding to 'ipc:///tmp/tester' will create the file
/tmp/tester. See issue 567 for more information.
* The INITIATE command vouch box is Box[C',S](C->S') instead of Box[C'](C->S),
as recommended by https://codesinchaos.wordpress.com/2012/09/09/curvecp-1/,
to reduce the risk of client impersonation.
* Mirrors the change in libcurve and CurveZMQ specifications.
* ZMQ_REQ_STRICT was negative option (default 1) which goes against
the standard, where defaults are zero. I renamed this to
ZMQ_REQ_RELAXED.
* ZMQ_REQ_REQUEST_IDS felt clumsy and describes the technical solution
rather than the problem/requirement. I changed to ZMQ_REQ_CORRELATE
which seems more explicit.
