- Update to 4.2.8p4 to fix several security issues (bsc#951608):
 * CVE-2015-7871: NAK to the Future: Symmetric association authentication
 bypass via crypto-NAK
 * CVE-2015-7855: decodenetnum() will ASSERT botch instead of returning
 FAIL on some bogus values
 * CVE-2015-7854: Password Length Memory Corruption Vulnerability
 * CVE-2015-7853: Invalid length data provided by a custom refclock
 driver could cause a buffer overflow
 * CVE-2015-7852 ntpq atoascii() Memory Corruption Vulnerability
 * CVE-2015-7851 saveconfig Directory Traversal Vulnerability
 * CVE-2015-7850 remote config logfile-keyfile
 * CVE-2015-7849 trusted key use-after-free
 * CVE-2015-7848 mode 7 loop counter underrun
 * CVE-2015-7701 Slow memory leak in CRYPTO_ASSOC
 * CVE-2015-7703 configuration directives 'pidfile' and 'driftfile'
 should only be allowed locally
 * CVE-2015-7704, CVE-2015-7705 Clients that receive a KoD should
 validate the origin timestamp field
 * CVE-2015-7691, CVE-2015-7692, CVE-2015-7702 Incomplete autokey data
 packet length checks
- Use ntpq instead of deprecated ntpdc in start-ntpd (bnc#936327).
- Add a controlkey to ntp.conf to make the above work.
- Improve runtime configuration:
 * Read keytype from ntp.conf
 * Don't write ntp keys to syslog.
- Don't let 'keysdir' lines in ntp.conf trigger the 'keys' parser.
- Fix the comment regarding addserver in ntp.conf (bnc#910063).
- Remove ntp.1.gz, it wasn't installed anymore.
- Remove ntp-4.2.7-rh-manpages.tar.gz and only keep ntptime.8.gz. The rest
 is partially irrelevant, partially redundant and potentially outdated
 (bsc#942587).
- Remove 'kod' from the restrict line in ntp.conf (bsc#944300).
- Use SHA1 instead of MD5 for symmetric keys (bsc#905885).
- Require perl-Socket6 (bsc#942441).
- Fix incomplete backporting of 'rcntp ntptimemset'.");
