Focus: Bug fixes

Severity: Medium

This is a recommended upgrade.

This release updates sys_rootdisp and sys_jitter calculations to match
the RFC specification, fixes a potential IPv6 address matching error
for the "nic" and "interface" configuration directives, supresses
the creation of extraneous ephemeral associations for certain
broadcastclient and multicastclient configurations, cleans up some ntpq
display issues, and includes improvements to orphan mode, minor bug
fixes and code clean-ups.

New features / changes in this release:

ntpd

* Updated "nic" and "interface" IPv6 address handling to prevent
mismatches with localhost [::1] and wildcard [::] which resulted from
using the address/prefix format (e.g. fe80::/64)
* Fix orphan mode stratum incorrectly counting to infinity
* Orphan parent selection metric updated to includes missing ntohl()
* Nonprintable stratum 16 refid no longer sent to ntp
* Duplicate ephemeral associations suppressed for brodcastclient and
multicastclient without broadcastdelay
* Exclude undetermined sys_refid from use in loopback TEST12
* Exclude MODE_SERVER responses from KoD rate limiting
* Include root delay in clock_update() sys_rootdisp calculations
* get_systime() updated to exclude sys_residual offset (which only
affected bits "below" sys_tick, the precision threshold)
* sys.peer jitter weighting corrected in sys_jitter calculation

ntpq

* -n option extended to include the billboard "server" column
* IPv6 addresses in the local column truncated to prevent overruns
