[evolution-data-server/camel-socks-proxy] Make _set_errno_from_pr_error() public

[Federico Mena Quintero <federico src gnome org>]

commit 4830afcea71076dde64ba106e2045a8cbbc9a812
Author: Federico Mena Quintero <federico novell com>
Date:   Thu Jul 15 15:17:06 2010 -0500

    Make _set_errno_from_pr_error() public
    
    We need to use this both in the raw TCP stream and in the SSL one.
    Maybe later we can switch to full exceptions.
