net_sched: sch_fq: enable in-kernel pacing for QUIC servers

Willem added GSO support to UDP stack, greatly improving performance
of QUIC servers.

We also want to enable in-kernel pacing, which is possible thanks to EDT
model, since each sendmsg() can provide a timestamp for the skbs.

We have to change sch_fq to enable feeding packets in arbitrary EDT order,
and make sure that packet classification do not trust unconnected sockets.

Note that this patch series also is a prereq for a future TCP change
enabling per-flow delays/reorders/losses to implement high performance
TCP emulators.
