Some parts in eZ use the HTTP_X_FORWARDED_FOR and REMOTE_ADDR to evaluate the clients ip.

For example eZDebug doesn`t use HTTP_X_FORWARDED_FOR which makes troubles when working through a proxy.

I propose the we add a new function to eZSys that evaluates the client ip ( eZSys::clientIP() ).

All parts of eZ (eZDebug, eZSession) should use in the future eZSys::clientIP() to determine the ip.

You can find all parts by grepping for REMOTE_ADDR.
