[Federico Mena Quintero <federico src gnome org>]

commit d59da86912ec590028573997f3d30f4c1ae37622
Author: Federico Mena Quintero <federico novell com>
Date:   Wed May 12 15:00:54 2010 -0500

    Add camel_session_set/get_socks_proxy()
    
    This is the only API that clients should need to call to
    set a SOCKS proxy for Camel's TCP connections.
