This helps the ntp process to a) give a better pledge(2) and to b)
keep the promise of "saving the world again... on time" by removing
the delays that have been introduced by expensive constraint forks.
The new design offers better privsep but introduces a few more imsgs
and runs a little bit more code in the privileged parent. The
privileged code is minimal, carefully checked, and does not attempt to
"parse" any contents; the forked constraints instantly drop all
privileges and pledge to "stdio inet".

including fork/exec cost, it would be better if constraints were
forked from the master process, which would then tell the ntp
engine. That would increase accuracy and security.
Lots of conversations with reyk and bcook
in asn1 and x509 code, all dealing with an ASN1_TIME. This brings the parsing
together in one function that converts into a struct tm. While we are at it this
also brings us into conformance with RFC 5280 for times allowed in an X509 cert,
as OpenSSL is very liberal with what it allows.

- verify that kbd is executable and kbdtype is not empty
- use safer 'print --' to pipe the initial pf ruleset to pfctl
- simplify the ipsecctl if-block

development of a cargo cult in case people look at existing files
for examples. This achieves a consistent .Fo and .Fn quoting style
across the whole tree.
MD4 should have been removed a long time ago. Also, RFC 6150 moved it to
historic in 2011. Rides the major crank from removing SHA-0.
Discussed with many including beck@, millert@, djm@, sthen@

- run domainname only with a non-empty /etc/defaultdomain file
- Make single-user if-block more intuitive, which also matches
better what the comment actually says
OK halex@, krw@ on a similar diff
