HAMMER VFS - Implement Version 6 features as WIP (work in progress)
* Add a new directory hash which generates segmented CRC and then adds
them together for the filename.
This tends to result in a directory key offset instead of a complete
re-randomization when a temporary file extension is renamed to its base
filename.
Numerous programs create temporary files and then rename them. This
tends to maintain inode number / directory name entry ordering a bit
better.
* This is a work in progress version. Production systems should not upgrade
their HAMMER filesystem to version 6 at this time.
