Survey pattern is "multicast with reply". There are two roles:
surveyor and respondent. Surveyor publishes a survey which gets
delivered to all connected respondents. Each repondent can send
a response to the survey. All the responses are delivered to
the original surveyor. Once the surveyor decides that the survey
is over (e.g. deadline was reached) it can send initiate survey.
Late responses from old surveys are automatically discarded by
the surveyor socket.
Socket types: SURVEYOR, XSURVEYOR, RESPONDENT, XRESPONDENT
Patch also includes a test program with surveoyr, two respondents
and an intermediary device.

When reconnection happened, identity was not resent to the peer.
Fixed.

The relationship of these two classes was 1:1.
Thus one of them was obsolete.

This is more consistent with adjacent add_fd and rm_fd functions.

However, the "durable socket" behaviour wasn't re-added.
Identities are used solely for routing in REQ/REP pattern.

This patch adds support for checking messages as they arrive
(as opposed to when they are recv'd by the user) and drop
the connection if they are malformed.
It also uses this new feature to check for validity of inbound
messages in REQ socket.

This is a preliminary patch allowing for socket-type-specific
functionality in the I/O thread. For example, message format
can be checked asynchronously and misbehaved connections dropped
straight away.
