lvm2/lib/report/report.c
Zdenek Kabelac ecfb90de74 report: convert more options to use single status 
Convert fields into using a single status ioctl call per LV.
This is a bit tricky since when there are more complicated
stacks, at this moment its undefined which values should be shown.

It's clear we need to cache more then single ioctl per LV,
but also we need to define more explicitely relation between
reported values for snapshots.

This patch is not a final state, rather a transitional step.
It should not be giving more 'worst' values then previous
many-ioctl-calls-per-lv solution.
