[Cake] dynamic tuning cake to the actual bandwidth via measurement

[Dave Taht]

Various means of doing dynamic tuning have been proposed (ping, udp
with short TTLs, etc), but a control interface to do it has as yet
been hard. Tuning the cake
bandwidth parameter should be (is?) as simple as

tc qdisc change dev eth2 bandwidth 49mbit # 40mbit etc

And thus we could finally add a dynamic tuning/measurement facility
that drives that dynamically to get a good setting.

See also gargoyle router projects's live estimator code as an example that could
be seriously simplified to drive cake.
