    Rewrite vldb_check -fix
    
    vldb_check -fix was very 'topical' in nature.  It showed signs that
    each sucessive corruption had been treated as a one off needing a
    specific fix.  This made the code difficult to understand and
    incomplete: for instance a single volume on the wrong hash only was
    not corrected.  Further there was some rather unfortunately code which
    would under certain circumstances stamp the last volume at various
    places across the file.
    
    This checkin removes all the old code and replaces it with a
    'systematic' fix.  During the last scan across all the volumes, all
    four of the hash chains are rebuild from the ground up.  We can then
    get rid of the outer 'Mung Until Now Good' iteration and further we
    benefit from a linear run time.
    
    Tested by building several different forms of broken-ness in all three
    chains and then fixing it.
    
    Now with improved logging and correct non insertion of nonexistant elements
    and clean compiled with extra warning.
