Adding stream timeouts

[michaldobrodenka]

Sometimes on poor connections I'm experiencing Thread pool deadlock, it seems like EndRead in SSL stream waits forever. Hope this will improve situation. I have seen similar problem with connect also.

Try/catch around Dispose was necessary on iOS with Xamarin, if stream was already Disposed (app went foreground), Dispose crashed app with exception.
