no need to request it ever again.  The only exception is the
escalation of failed constraint checks that might lead into
re-requesting the constraint time from all servers.  Adjust the states
accordingly.

time from HTTPS servers, by parsing the Date: header, and use the
median constraint time as a boundary to verify NTP responses.  This
adds some level of authentication and protection against MITM attacks
while preserving the accuracy of the NTP protocol; without relying on
authentication options for NTP that are basically unavailable at
present.  This is an initial implementation and the semantics will be
improved once it is in the tree.

If the network is unreachable when ntpd starts and host_dns fails, be sure
that we still close the HOST_DNS imsg.

Old drift files will be interpreted as a minuscule adjustment and
ntpd will proceed to rediscover the drift, like starting from zero

- Nothing seems to free the result of host_dns(), so add host_dns_free() and
call after each query.
- If imsg_add() fails, it frees buf. Avoid subsequently dereferencing the
freed buf in imsg_close().

peanuts -- but all work has to start somewhere.

I mirrored from smtpd a little too literally.

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

This avoids a namespace conflict with Solaris build environments.

Switch to local definitions where MAX is needed.

Nothing is done with the return value from ntp_dns, and it already calls
fatal() on failure.
