patch to upgrade

This release has bug fixes and some new options.  The new commandline
option for nsd '-v' shows the configure line and library versions.  The
log-only-syslog option stops duplicate log messages with systemd if
enabled.  And the min-expire-time option stops zones from having an
expire time that is too low, forcing too much effort by zone fetching.
