Add a new "REFCOMPRESSRATIO" property.
For snapshots, this is the same as COMPRESSRATIO, but for
filesystems/volumes, the COMPRESSRATIO is based on the data "USED" (ie,
includes blocks in children, but not blocks shared with the origin).
This is needed to figure out how much space a filesystem would use if it
were not compressed (ignoring snapshots).
