[Cake] fq_codel_fast

[Dave Taht]

It has been a long time since I profiled the kernel on small platforms.

* tc filtering has got rcu'd
* routing lookup code "improved"
* flow dissector grew massively
* fq_codel grew "features"

Anyway, this should be a drop in replacement (presently) for fq_codel,
that compiles out of tree and rips out almost everything I don't like.

I think the tc filter thing really hurt us in cake.

gonna go profile, then maybe add in ye olde shaper
