The volume directory may have 2^16 (=65536) directories because
prefix length of object pathname is 4 bytes. But ext3 filesystem can
only have EXT_LINK_MAX (32000) directories.
This changes the prefix length from 4 bytes to 3 bytes and breaks
the volume data format compatibility with older version.
Now the maximum count of links in volume directory is 2^12 (=4096)
and it doesn't exceed ext3's upper limit of max links.
