* Not setting the http.socket.rcv-buffer-size and http.socket.snd-buffer-size properties unless the user has specified them explicitly. This will cause Synapse to use platform defaults when appropriate. (see the thread: HTTP Core Performance and Reactor Buffer Size)
* Updated the relevant documentation and test cases.
* Changed the EchoHttpServerController to reuse server sockets when appopriate.
