=head2 make_short_dir_version($longstring)

    Transform the given string into one that is at most 70 characters long.
    That is done in two steps:
    - Cut all parts separated by '_' or '-' down to a length of 5.
    - Cut down the result to a length of 60 and fill it up to length 70
      with the MD5 checksum.

    This transform always returns the same result for the same string.
    There is no counter and reference to a global set of names to make the string unique.

=head2 get_unique_name ($hostname, $unique_map, $shortdirhash, $shortdirhashreverse)

    Return a long and a short unique name for the given $hostname.
    Despite the function name and unlike the generation of unique
    names for files, the returned names are not really unique.  Quite
    the opposite.  The returned names are quaranteed to return the
    same result for the same input.

    The returned short name has at most length 70.

=head2 check_unique_directorynames($directories)

    The one really important check is made in get_unique_name().  It
    checks that get_unique_name() is not called twice for the same
    directory host name.  The tests in this function contain the
    legacy tests that basically only check if there where a collision
    of the partial MD5 sum that is used to make the short unique names
    unique.

    The maps $unique_map, $shortdirhash, $shortdirhashreverse are used
    only to check that _different_ input names are mapped to different
    results.  They are not used to influence the result.  That assumes
    that this function is called only once for every directory
    hostname.
