2009-05-09 Tatsuhiro Tsujikawa <[email protected]>

	Removed --enable-http-server and --http-server-listen-port
	options.  Added --enable-xml-rpc and --xml-rpc-listen-port
	instead.  The original feature for --enable-http-server that
	reports download progress in HTML was officially removed.  Persist
	XML-RPC connection if client supports keep-alive.
