 - blk_equals() is too strict.  If the journal entry defines more frags    than we're claiming it should still be considered an exact match.  This    would previously leak frags that had been extended.  - If there is a sequence number problem in the journal print the sequence    numbers we've seen so far for debugging.  - Clean up the block mask related debuging printfs.  Some are redundant.
