	* HttpReplyChannel.cs, HttpChannelListener.cs, HttpListenerManager.cs:
	  Refactoring on listener manager to correctly handle wsdl and help
	  requests for such case that they conflict in addressing. Now it
	  can correctly distinguish service calls, WSDL requests and help
	  requests when all of them point to "http://localhost/foo.svc"
	  (which is very common case that the user does not change Http*Url).

	* ServiceMetadataExtension.cs : restructure internal channel property
	  so that http channels can cope with it.
