  Modified files:
    sys/ufs/ffs          ffs_extern.h ffs_snapshot.c 
    sys/ufs/ufs          ufs_extern.h ufs_lookup.c 
  Log:
  Several small but important fixes for snapshots:
  
  1) Be more tolerant of missing snapshot files by only trying to decrement
     their reference count if they are registered as active.
  
  2) Fix for snapshots of filesystems with block sizes larger than 8K
     (from Ollivier Robert <roberto@eurocontrol.fr>).
  
  3) Fix to avoid losing last block in snapshot file when calculating blocks
     that need to be copied (from Don Coleman <coleman@coleman.org>).
