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.

If several of the outbound pipes become passive while sending
a single message, the refcount on the message is adjusted
once only, not multiple times. It's an atomic operation so
the cost is not negligible.

When exec is executed to start a different process image old
0MQ file descriptors could stay open, thus blocking TCP ports
and alike. This patch should solve the problem.

On win64 the size of file descriptor is not the same as size of int.
The bug in PGM transport caused a runtime error because of this.
The problem is fixed now.

The engine was not used exclusively for TCP connections.
Rather it was used to handle any socket with SOCK_STREAM
semantics. The class was renamed to reflect its true function.
