CVS commit: src/sys/kern

["Robert Elz" <kre%netbsd.org@localhost>]

Module Name:    src
Committed By:   kre
Date:           Sat Apr 14 01:45:37 UTC 2018

Modified Files:
        src/sys/kern: subr_prf.c

Log Message:
Allow the precision of the sub-second field of timestamps to
be controlled - for now that is done by editing this file and
recompiling (or using gdb or equiv to patch /netbsd or /dev/kmem)
but adding a sysctl to allow dynamic userland control should be easy.

Also reduce the initial seconds field width of timestamp from 5 to 4
(it grows wider as needed.)

Avoid printing timestamps if we cannot be sure there will be
a message to accompany them.   (Observed happening...)
