Subject: [PATCH 2/9] tproxy: added const specifiers to udp lookup functions

From: Balazs Scheidler <bazsi@...abit.hu>

The parameters for various UDP lookup functions were non-const, even though
they could be const. TProxy has some const references and instead of
downcasting it, I added const specifiers along the path.
