	* System.Net/WebConnection.cs: attach a validation callback to the new
	event in Mono.Security.
	* System.Net/ServicePointManager.cs: added a new ValidationHelper
	class that takes care of building the certificate chain and perform
	all the check that were done in Mono.Security before. This way the 2.0
	server certificate validation callback can get all the data it needs.
	* System.Net.Security/SslStream.cs: don't do anything if a chain
	element has no error.

	Fixes bug #584050.
