mjl 6299fb0813 Correct nokerninfo tty flag being left set in most error cases. 
Closes PR/7388 by Dave Huang <khym@bga.com>.

sommerfe 79b9ef47d2 Don't bother doing stddev calculation when n==1, since that results in 
a computation of 0.0/0.0.
On IEEE systems you get a NaN from this; non-IEEE systems probably
give you a SIGFPE.

jwise bce8ed1c8e Once more around the hickory shrub. Faster and simpler stddev calculation from 
Bill Studenmund.

jwise 12711b010a Add code from Daniel Hagerty <hag@ai.mit.edu> to print standard deviation

tv 8f7ed4aa27 Restrict -l to the superuser as suggested in PR 3973 from <soren@t.dk>. 
Also distinguish "-f" from "-i 0.x" in the superuser restriction messages.

tv b6b7269733 Nuke the termios stuff from the 1997/03/11 import, which prevents ping 
from being run in the background of most shells without redirecting stdin
from /dev/null.  (AFAICT, the termios stuff is useless and does not
interfere with SIGINFO handling.)

cgd 705e61651e fix a couple of bugs pointed out by John Birrell, though fix some 
differently he did.  (1) don't assume that the timeval in
the packet is correctly aligned, (2) don't compare beyond the end
of the packet, (3) minor cast for printf happiness.
