Revert of Replace StreamListenSocket with StreamSocket in HttpServer.

Revert of Replace StreamListenSocket with StreamSocket in HttpServer. (patchset #29 of https://codereview.chromium.org/296053012/)

Reason for revert:
looks like it caused net_unittests failures: http://build.chromium.org/p/chromium.win/builders/Vista%20Tests%20(2)/builds/44610/steps/net_unittests/logs/MultipleRequestsOnSameConnection

Original issue's description:
> 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.
>
