log a warning one time when we can't open or write the drift file;
also add "(no drift file)" to the adjfreq log message on failure;
ok henning@

just call getpwnam(NTPD_USER) once; ok henning@

revert SIGQUIT catching; requested by deraadt

catch SIGQUIT too. ckuethe@ and henning@ ok.

if the drift file is missing, reset adjfreq to zero; iirc diff from Glaser
from a long time ago. ok ckuethe@

add -n to usage();

Provide the -n switch like in the other imsg daemons for testing
the configuration file.
"yes please, ok" henning@

Allow ntpd to log sensor offsets and adjtime calls to syslog at LOG_DEBUG
priority.

don't write anything to log until we are daemonized. spotted by

Reset adjtime() on startup; having an adjtime() active while starting
up causes overcompensation and confusing debug log entries; noticed
by dtucker@

Save the computed clock drift and use it on startup. ok deraadt@

avoid a race by installing SIGCHLD handler before fork() is called.

Import frequency conrrection code from dragonfly, whith some changes:
only do frequency compensation if the clock is synced, and a slightly
diffent way of computing the linear regression.

You'll need a recent kernel and libc to use this.
Testing by naddy@ and ckuethe@ and others, thanks!

Compensate old offsets with the amount of adjustment done, avoiding
overcompensating. From DragonFly, uses recent adjtime(2) changes,
so you'll need a recent kernel. ok henning@

handle -1 return from host_dns(); ok henning@

when running ntpd with "-s" as it's argument from /etc/rc.conf, make sure the
output goes to syslog and not console by moving around log_init

OK henning@, markus@ and mblamer@

More descriptive error if a signal causes the child to exit; ok henning@

use a #define for the time to wait on -s and clarify a log msg
