[tproxy] [PATCH 05/11] TProxy: added const specifiers to udp lookup functions

[Balazs Scheidler]

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.
