cangw: support new can-gw features for Linux 3.9+

Browse Source 
Added new option '-i' for can-gw rules to allow to route CAN frames back to the
originating/incoming CAN interface (which is disabled by default).

CAN frames that are deleted due to the violation of the max_hops limit are now
printed when displaying the configured rules with 'cangw -L'.
