[SCHED]: Qdisc changes and sch_rr added for multiqueue

Add the new sch_rr qdisc for multiqueue network device support.  Allow
sch_prio and sch_rr to be compiled with or without multiqueue hardware
support.

sch_rr is part of sch_prio, and is referenced from MODULE_ALIAS.  This
was done since sch_prio and sch_rr only differ in their dequeue
routine.
