Reduces the number of log.c snowflakes by a little, and gives ntpd a
variadic fatal() function to be used later.

NB: this utility has only one option, and it's not optional! i haven;t
marked -s as being mandatory, since hopefully someone will make
ntpctl run without arguments do something useful;

* For time_t values, use the printf("%lld", (long long)t) idiom.
* Don't print "Invalid program name" in usage() when main() just runs ntpd.
* Make "Show/Shows" consistent in the manual, sort .Xr and correct .Ox.

diffent way of computing the linear regression.
You'll need a recent kernel and libc to use this.
