[PATCH, RFC] default to inode64 on 64-bit systems

I think such a mount option would be a must. There is lots of 32-bit Software that cannot cope with 64-bit inodes. Unfortunately there are closed-source 32-bit apps (which can be run on 64 bit systems) where nothing can be done for 64-bit inode compatiblity in the short term. Had this problem very recently with the Zmanda Enterprise Backup Software, which forced me to remove the inode64 option.
