QPID-5363: Add locks to prevent race condition in Amqp 1.0 transport handler.
Windows clients occasionally crash on exit handling simultaneous
eof() and close() on separate threads.
> C++ HelloWorld messaging client crash closing AMQP 1.0 connection on Windows

> Key: QPID-5363
> URL: https://issues.apache.org/jira/browse/QPID-5363
> Project: Qpid
> Issue Type: Bug
> Components: C++ Client
> Affects Versions: 0.25
> Environment: Windows, native C++ client, Amqp 1.0 protocol, Visual
> Studio 2008, 32-bit, Debug
> Reporter: Chuck Rolke
>
> HelloWorld connects, send all messages, and then crashes with an access
> violation during connection::close(). Gordon and I tracked the issue down to
> a double free of TcpTransport aio objects, with the __vftable containing all
> 0xdddddddd pointers indicating that the object was already deleted.
> Without the proposed fix, a locked 'closed' flag, the code crashes about 10%
> of the time. With the fix it proceeds indefinitely.
