Change routing API

Now 'From' and 'To' arguments must be omitted in functions
and structures related to routing.
The commit deprecates the following functions:
     ejabberd_router:route/3 in favor of ejabberd_router:route/1
     ejabberd_router:route_error/4 in favor of ejabberd_router:route_error/2
     ejabberd_local:route_iq/4 in favor of ejabberd_local:route_iq/2
     ejabberd_local:route_iq/5 in favor of ejabberd_local:route_iq/3
The format of {route, From, To, Packet} is changed in favor of {route, Packet}
