Log Message:
fix a long-standing scheduler problem that p_estcpu is doubled
for each fork-wait cycles.

- updatepri: factor out the code to decay estcpu so that it can be used
  by scheduler_wait_hook.
- scheduler_fork_hook: record how much estcpu is inherited from
  the parent process.
- scheduler_wait_hook: don't add back inherited estcpu to the parent.
