Till now the code was spread over mutliple locations.
Additionally, the code was made more formally correct,
with explicit pipe state machine etc.

So far, the pipe termination code was spread among socket type
classes, fair queuer, load balancer, etc. This patch moves
all the associated logic to a single place.

So far, there was a pair of unidirectional pipes between a socket
and a session (or an inproc peer). This resulted in complex
problems with half-closed states and tracking which inpipe
corresponds to which outpipe.
This patch doesn't add any functionality in itself, but is
essential for further work on features like subscription
forwarding.

This patch addresses serveral issues:
1. It gathers message related functionality scattered over whole
codebase into a single class.
2. It makes zmq_msg_t an opaque datatype. Internals of the class
don't pollute zmq.h header file.
3. zmq_msg_t size decreases from 48 to 32 bytes. That saves ~33%
of memory in scenarios with large amount of small messages.

On-disk storage should be implemented in devices rather than
in 0MQ core. 0MQ is a networking library and there's no point
in storing network buffers on disk.

Specifically, shutdown of child objects is initiated *before* termination
handshake with socket object.

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.

The msgs_written variable keeps track how many complete
messages have been written so far. The rollback operation drops all
fragments of the last incomplete message so it shouldn't
change this variable at all.

This commit introduces the necessary changes necessary
for implementing flow control. None of the socket types
implements the flow control yet. The code will crash when
the flow control is enabled and the thw lwm is reached.
The following commits will add flow-control support for
individual socket types.
