There is long-standing consensus that err(1, NULL) is the best idiom
after failure of malloc(3) and friends.

Based on an original idea and a different patch from landry@.
OK jung@ zhuk@ landry@
krw@ agreed to the general idea

process management of the contraint processes has been moved from ntp
to the parent, for better privsep and pledge, but the ntp process
still attempted to kill the constraints on timeout directly.  Fix this
regression by introducing a new imsg from ntp to the parent and the
related logic to kill a constraint at the right place.

The 'A' option elevated warnings to errors, and has been the default for some
time. Then warnings were effectively eliminated in favor of everything
being an error, but then the 'a' flag turned real errors into warnings!
Remove the 'a' option entirely. You shouldn't have used it anyway.

Work around this particular case by reseeding whenever pid=1, but as guenther@
notes, directly calling clone(2), and then forking to match another pid,
provides other ways to bypass new process detection on Linux.
Hopefully at some point Linux implements something like MAP_INHERIT_ZERO, and
does not invent a corresponding mechanism to subvert it.
