Module Name:    src
Committed By:   mrg

Modified Files:
        src/usr.bin/vmstat: vmstat.c

Log Message:
move the time nlist fetches into their own namelist and only
fetch them when necessary.  allow for fallback uses of older
time sources if others are not present.

this stops vmstat from exiting if it can't get the addresses
of these time values it often doesn't need (eg, running kernels
use the sysctl method), which has cropped up recently wit the
removal of boottime variable.

a slighly modified version of this patch (modified to handle
the old boottime variable over the new one) works against a
netbsd-9 vmstat in -current too.
