kernel - usched_dfly revamp (3), fix estcpu

* Fix the estcpu calculation, which previously assumed only a single
  runq (in usched_dfly there is a runq per cpu).

* Add a global atomic int accounting for all running and runnable lwp's.

* Fix cpu-hogging issues for bursty processes by creating a fast-decay-mode
  for estcpu when a thread first starts up, or after it has been asleep
  for more than 1 seconds.
