intelli_plug: use rq_stats to help detect artificial or constant loads

benchmarks often create fake / artificial loads at a constant rate.  These
type of loads are not detected corectly by run average algorithms. Use
the run queue stats to help detect these cases and bring up the cores in
correspondence.

intelli_plug: use mp_decision() algorithm for core 3 and 4

This replaces the simplistic check for run queue thresholds with a more
sophisticate algorithm with time awareness

intelli_plug: use mp_decision to reduce online persistence count for cores

this should bring down the cores faster when run queue is low
also optimized code a bit using local vars

this will reduce the jumpiness of hotplug decisions

intelli_plug: disable by default

let the user enable via sysfs so it won't clash with mpdecision which is
enabled by default for qualcomm phones

intelli_plug: slow down hotplug activity from 50ms to 200ms

this will reduce the hotplug chaos which may in turn save more power

sched: Change rq->nr_running to unsigned int

Since there's a PID space limit of 30bits (see
futex.h:FUTEX_TID_MASK) and allocating that many tasks (assuming a
lower bound of 2 pages per task) would still take 8T of memory it
seems reasonable to say that unsigned int is sufficient for
rq->nr_running.

When we do get anywhere near that amount of tasks I suspect other
things would go funny, load-balancer load computations would really
need to be hoisted to 128bit etc.

So save a few bytes and convert rq->nr_running and friends to
unsigned int.
