[Miwi-middleware] Boost.asio seems not to forward the request to the handler

[Mathias Hablützel]

Hi Dmitri (et al),

After trying to decouple the boost.asio io_service with an opaque handler,
the compilation passed very well, but failed the test. It looked like there
are simply no responses from the server. After further investigation I
added some debug messages in the code to find out where the calls go
through and found out that the callback for handling the incoming request
is simply never called.

Here I miss a call to handleRead. It simply never seem to happen.

There is a call missing to BufferedTcpConnection::handleRead and this seems
to be the reason why the tests fail.

Can you spend some time helping me with debugging this issue? Is Philipp
Slusalek ok with it?

Thank you very much
Mathias
