    HAMMER - Add additional warnings for v2/v3 upgrades, fix bug in snaprm
    
    * Add warnings related to backup scripts when upgrading from V2 to V3.
      The synctid directive does not generate a snapshot.  You should generate
      a real snapshot to properly track them.
    
      Also, removing a snapshot softlink does not remove the meta-data and
      thus the pruning code will continue to prune around that snapshot.
      The snaprm directive should be used when removing snapshot softlinks
      to also remove the meta-data.
    
    * Snaprm now uses the current directory when removing a transaction id
      and no target directory was specified.
    
    * Snaprm now makes it clear that a failure to remove meta-data when
      removing a softlink is just a warning, not a fatal error.
