yamt 8ab7495c2d make scheduler work better when a system has many runnable processes 
by making p_estcpu fixpt_t.  PR/31542.

1. schedcpu() decreases p_estcpu of all processes
   every seconds, by at least 1 regardless of load average.
2. schedclock() increases p_estcpu of curproc by 1,
   at about 16 hz.

in the consequence, if a system has >16 processes
with runnable lwps, their p_estcpu are not likely increased.

by making p_estcpu fixpt_t, we can decay it more slowly
when loadavg is high.  (ie. solve #1.)

i left kinfo_proc2::p_estcpu (ie. ps -O cpu) scaled because i have
no idea about its absolute value's usage other than debugging,
for which raw values are more valuable.
