New patch at the end this time, getting rid of rt->rt_dst :-)

Most recent performance numbers:

> 1) Output route lookup: ~2150 cycles
> 2) Input route lookups: ~2600 cycles (rpfilter=0)
>                         ~3700 cycles (rpfilter=1)

How things stand now:

1) Output route lookup: ~1600 cycles
2) Input route lookups: ~2200 cycles (rpfilter=0)
                        ~3100 cycles (rpfilter=1)
