Matt Ahrens f5fc4acaa7 Illumos #1092: zfs refratio property 
Add a "REFRATIO" property, which is the compression ratio based on
data referenced. 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).
