Replace StreamListenSocket with StreamSocket in HttpServer.

    
1) HttpServer gets ServerSocket instead of StreamListenSocket.
2) HttpConnection is just a container for socket, websocket, and pending read/write buffers.
3) HttpServer handles data buffering and asynchronous read/write.
4) HttpConnection has limit in data buffering, up to 1Mbytes by default.
5) For devtools, send buffer limit is 100Mbytes.
6) Unittests for buffer handling in HttpConnection.
