[libsoup] Make default property values/features more sane on plain SoupSession

[Dan Winship <danw src gnome org>]

commit 6863c37db17db41ec027d3b17f0b9d5d0be96c72
Author: Dan Winship <danw gnome org>
Date:   Thu Oct 6 10:26:57 2011 -0400

    Make default property values/features more sane on plain SoupSession
    
    (can't do this for SoupSessionAsync/SoupSessionSync because of
    backward compatibility)
    
    Also, make it illegal to set certain deprecated properties on a plain
    SoupSession.
