    Port from ZODB 3.2.
    
    Stop believing the maximum oid cached in a FileStorage's .index file.
    
    This is a critical bugfix, although the problems it addresses are
    (a) rare; and, (b) not entirely fixed yet (more checkins to come).
    
    The true max oid is found efficiently now by exploiting the recently-added
    fsIndex.maxKey() method (which was, of course, added for this purpose).
    
    Also fix that the .index file could get updated on disk when the
    FileStorage was opened in read-only mode.  The code was trying to prevent
    this, but missed the most obvious rewrite path.
    
    Incidentally improved many obsolete and/or incorrect comments.
