Added link call to AVMService. It essentially creates a hard link

without the bad aftertaste.  It's needed for the AVMSyncService's
update method which will move new versions of nodes from one AVM
tree to another.  Also a checkpoint for AVMSyncService. One can safely
call compare and get back an empty List of AVMDifferences.
