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.

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.

Multicast loopback is not a real multicast, rather a kernel-space
simulation. Moreover, it tends to be rather unreliable and lossy.
Removing the option will force users to use transports better
suited for the job, such as inproc or ipc.

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

If the peer getting the message have disconnected in the middle
of multiplart message, the remaining part of the message went
to a different peer. This patch fixes the issue.

When new peer connects to a PUB socket while it is in the middle
of sending of multi-part messages, it gets just the remaining
part of the message, i.e. message atomicity is broken.
This patch drops the tail part of the message and starts sending
to the peer only when new message is started.

Compilation of ip.cpp have failed because EPROTONOSUPPORT
was undefined. Including zmq.h should help as the error
code is defined there.

The new option allows user to guard against peers sending
oversized messages. Connection to peer sending oversized message
is dropped.

This means that all the handshaking while accepting incoming
connection is done exclusively in I/O threads, thus it won't
overload the application thread's mailbox.

So far ZMQ_RECONNECT_IVL delay was used only when TCP connect
failed. Now it is used even if connect succeeds and the peer
closes the connection afterwards.

- ctx constructor was calling mailbox_t constructor implicitly
- moved WSAStartup and WSACleanup to be outside constructor/destructor

Reaper thread destroys the socket asynchronously.
zmq_term() can be interrupted by a signal (EINTR).
zmq_socket() will return ETERM after zmq_term() was called.

The internal log socket was subtracted from the number of
available sockets. So, if max_sockets was set to 100,
you could create only 99 sockets. Fixed.
