Description
Short of a primitive to cheaply move extents of keys from object a to object b we will have to live with lazily cleaning up the snap collection mapping on the parents and children during future trims.
1) add support to SnapMapper for an hobject mask
2) add support to SnapMapper for invisibly removing filtered objects
Split will simply clone the snap mapping object off into the child objects and apply
more constrictive masks to the parent and child maps. Clone is copy on write as
well, so this operation should be bounded time not unduly hold up the split transaction.
