cpacfstatsd now correctly handles offline cpus and dynamically attaches to
cpus once they get online. If events are enabled when a hotplug event
occurs, cpacfstatsd uses a pseudo-counter to notify user applications about
the occurence of this event and a potential data inaccuracy.
cpacfstats shows if a hotplug event has been detected since at least one
counter was activated. As soon as all counters are deactivated, the
hotplug detection state is reset.

libpfm does not yet include counters introduced with z15 in a release.
cpacfstatsd now implements its own counter logic to become independent
of the slow release cycles of libpfm.
