With a TCP frontend, it is possible to upgrade a connection to HTTP when the backend is in HTTP mode. Concretly the upgrade install a new mux. So, once it is done, the downgrade to TCP is no longer possible. So we must take care to never assign a TCP backend to a stream on this connection. Otherwise, HAProxy crashes because raw data from the server are handled as structured data on the client side. This patch fixes the issue #420. It must be backported to all versions supporting the HTX.
