MFC r204410: Include terminated threads in ps's process cpu time field.
When a kinfo_proc is filled, first fill_kinfo_proc_only() fills in
ki_runtime using p->p_rux.rux_runtime (all cpu time used by the process
including terminated threads). If information for a specific thread is
requested, fill_kinfo_thread() then overwrites this with the thread's
td->td_runtime (good). If not, fill_kinfo_aggregate() overwrote it with
the sum of all threads' td->td_runtime which does not include terminated
threads.
This affects ps(1)'s TIME field, not its %CPU field nor anything in
top(1).

MFC r203760: Improve time precision for grdc(6):
Traditionally, grdc would obtain time through time(3) which in turn gets
only the second part of clock (CLOCK_SECOND), and sleep for 1 second after
each screen refresh.
This approach would have two problems. First, we are not guaranteed to
be waken up at the beginning of a whole second, which will typically
exhibit as a "lag" on second number. Second, because we sleep for whole
second, and the refresh process would take some time, the error would
accumulate from time to time, making the lag variable.
Make grdc(6) to use time(3) to get time only at the beginning, and sample
time in CLOCK_REALTIME_FAST granularity after refreshing, and use the
nanosecond part to caculate how much time we want to sleep.
