os/filestore: (re)implement merge

Browse Source

Merging is a bit different then splitting, because the two collections
may already be hashed at different levels.  Since lookup etc rely on the
idea that the object is always at the deepest level of hashing, if you
merge collections with different levels that share some common bit prefix
then some objects will end up higher up the hierarchy even though deeper
hashed directories exist.
