Idlestat: Calculate core/cluster data properly
Current implementation for core/cluster data calculation is to look
for intersections of same state residency in cpu data after loading
all of the data. This fails to correctly record core/cluster data
for cases where all the contained cpus are in a low power state, but
are not using the exact same state.
To resolve this, core/cluster state needs to be evaluated at the
same time as the cpu events are being processes. The store_data()
function is modified to record not only the affected cpu changes,
but also the affected core and cluster. Supporting changes are added
throughout the source tree.
