Before doing any routing, the router print a warning if old structures

Browse Source 
are used. Then it converts the structures to the old format and route
them. The router doesn't care about the structures format but the
conversion is necesary for code called from this module.

In C2S and S2S, no conversion is done before calling
ejabberd_router:route/3.
