Description

vdevs currently have a packed nvlist for config stored in their on-disk labels. Instead of adding to this every time we want a new config, we can make a new ZAP for every vdev and store its object # instead. It's also confusing that the config is stored both in the label and in the MOS, and some fields of the config are only valid in the MOS (the version in the label could be out of date). These fields should be stored in the new per-vdev ZAP objects.
