send/recv now complies with POSIX by using raw buffers instead
of message objects and by returning number of bytes sent/recvd
instead of 0/-1.
The return value is changed accordingly for sendmsg and recvmsg.
Note that related man pages will be fixed in a separate patch.

The old timeout in microsecond haven't been compliant with
POSIX and was impractical at the same time.

On systems using GCC 4.0 or newer which support symbol visibility in shared
libraries, use -fvisibility=hidden and only export explict API functions
defined in zmq.cpp. We do not enable -fvisibility on MinGW since this uses a
separate mechanism (__declspec).

- RAND_bytes function resides in crypto library
- pollfd on AIX used 'reqevents' instead of events and 'retnevents'
instead of 'revents'

zmq_msg_close now empties the message on zmq_msg_close, thus not
leaving random data in the structure, that may be mistaken for
a valid message.

Macro ZMQ_VERSION represents the current version of 0MQ
Macro ZMQ_MAKE_VERSION(major,minor,patch) allows to create
a representation of the specified version.
The versions can be compared using simple <, >, ==, etc.
operators.

* Assertion to check that pgm_getaddrinfo is actually returning something.
* Missing pgm_connect call.
* Typo on TOS causing immediate abort.
* Placeholder calls for timeouts whilst continuing spin loop functionality.
* OpenPGM v5 now supports reference counting so remove init checks.
* Duplicate UDP unicast port setting, requires one unicast and one multicast.
* Incorrectly set socket rcvbuf size with sndbuf.
* Replace std::lexicographical_compare of TSI's with long word integer comparisons.
* pgm_socket_t::receive returns -1 on no data.
Trying to optimize out the case where items_[i]. events is 0 would
result in a bogus pollfds[i]. Similarly in the select()-based impl,
while not strictly necessary it's better to get ZMQ_FD even if
events is 0 since that detects ETERM and friends.
Rewrite the select()-based zmq_poll() implementation to use
ZMQ_FD and ZMQ_EVENTS.
Also fix some corner cases: We should not pollute revents with
unrequested events, and we don't need to poll on ZMQ_FD at all
if a pollitem with no events set was passed in.
Rewrite zmq_poll() to use ZMQ_FD and ZMQ_EVENTS introduced on the
wip-shutdown branch. Only do the poll()-based version of zmq_poll (), the
select()-based version will not compile at the moment.
Sockets may now be migrated between OS threads; sockets may not be used by
more than one thread at any time. To migrate a socket to another thread the
caller must ensure that a full memory barrier is called before using the
socket from the target thread.
The new zmq_close() semantics implement the behaviour discussed at:
http://lists.zeromq.org/pipermail/zeromq-dev/2010-July/004244.html
Specifically, zmq_close() is now deterministic and while it still returns
immediately, it does not discard any data that may still be queued for
sending. Further, zmq_term() will now block until all outstanding data has
been sent.
TODO: Many bugs have been introduced, needs testing. Further, SO_LINGER or
an equivalent mechanism (possibly a configurable timeout to zmq_term())
needs to be implemented.
