Add two attributes to fq: Horizon and HorizonDrop (which correspond to the
TCA_FQ_HORIZON and TCA_FQ_HORIZON_DROP attributes). The HorizonDrop attribute
specifies which policy to apply: drop (1, kernel default), cap delivery time to
horizon (0), and the Horizon attribute specifies the number of useconds before
applying the policy.
Add a new test TestFqHorizon to test the changes and as an example of usage.

Testing and functionality for the use of HFSC has been implemented.
The use of service curves is implenented closely as to how they behave
with the TC implementation.
Automated checks and testing were succesful.
New in kernel 4.5 is a type of qdisc for lightweight (no qdisc lock)
ingress/egress parsing, called clsact. Add support for such a qdisc
type.
One primary consumer of clsact is the bpf filter, add support for that
as well.
