    dir: Protect against circular hash chains
    
    The dir package didn't protect against circular hash chains when
    performing directory lookups. A corrupt directory could therefore
    cause a client or a fileserver to go into an endless loop if that
    directory contained a loop in its hash chain pointers.
    
    Fix this by exiting the lookup if the hash chain has more elements
    than the total number of entries in a directory. This maximum number
    of entries is taken as being (number of entries per page) * (max
    number of pages), which is considerably more than the real maximum
    value.
