use RMS for jitter. we're linking with enough libraries that libm is tiny. ok deraadt

initial cut at ntpd. it is just capable of answering (s)ntp4 requests with the local time for now. imsg/buffer and logging framework from bgpd, ntp protocol hackery with Alexander Guy

Move imsg into libutil and add a man page. Minor bump for libutil. Previous versions of this diff and man page looked at by various people. "you should just commit" deraadt

Add ntpctl(8), which allows us to query the locally running ntpd(8) process diff from Mike Miller <mmiller mgm51 com> (many thanks!) OK phessler@, henning@, todd@
11 years ago
Add support for "constraints": when configured, ntpd(8) will query the 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. Discussed with deraadt@ and henning@ OK henning@
