Log message:
Update to 5.7p4, provided by Paul B. Henson in PR 49930:

Changes since OpenNTPD 5.7p3
============================
* Added support for using HTTPS time constraints to validate NTP responses.

* Workaround a bug in the Solaris adjtime call that caused the olddelta to
  never reach 0, leading to continual sync/unsync messages from ntpd.

* Workaround an overflow on systems with 32-bit time_t. This can result in a
  failure to set the time if the initial clock is set later than early 2036.
  Systems with a 32-bit time_t should upgrade well in advance of this date, but
  today this helps with systems that boot with an invalid initial time.

Note:the HTTPS time constraints feature is not currently available
in pkgsrc due to the lack of libtls.

Log message:
Put back implementation of MASTER_SITE_OPENBSD.

Log message:
Revert "Define and use MASTER_SITE_OPENBSD.",
proposed/discussed is required for such changes.

Changes since OpenNTPD 5.7p2
============================
* Fixed issue resolving hostnames when the network is initially unavailable.
* Fixed process name logging on Linux and OS X.
* Fixed adjfreq failures on Solaris due to uninitialized struct timex.
* Support building on Linux musl libc.

Update to 5.7p2 based on PR 49583 by Paul B. Henson.

2015-01-20  OpenNTPD 5.7p2

	* Switched the drift file from an unscaled frequency offset to ppm.
	  The latter format is compatible with that of ntp.org.  This allows
	  easy switching between ntpd daemons
	* Fixed a memory leak in DNS lookups.
	* Added support for setting the process title on Linux and OS X.
	  The different processes are now possible to tell apart by role in
	  the process list.
	* Import NetBSD support.
	* Various bugfixes and refinements from the community.

2015-01-08  OpenNTPD 5.7p1

	* Support for a new build infrastructure based on the LibreSSL
	  framework. Source code is integrated directly from the OpenBSD tree
	  with few manual changes, easing maintenance.
	* Removed support for several OSes pending test reports and updated
	  portability code.
	* Supports the Simple Network Time Protocol version 4 as described in
	  RFC 5905
	* Added route virtualization (rdomain) support.
	* Added ntpctl(8), which allows for querying ntpd(8) at runtime.
	* Finer-grained clock adjustment via adjfreq / ntp_adjtime where
	  available.
	* Improved latency on heavily-loaded machines.

Log message:
Define and use MASTER_SITE_OPENBSD.

Log message:
remove unavailable one from MASTER_SITES.
