Use the same API as the example code.
Allow the initial hash value to be passed in, as the examples do.
Incrementally hash in the dvp->v_id (using the official api) rather than
add it. This seems to help power-of-two predictable filename trees
where the filenames repeat on a power-of-two cycle and the directory trees
have power-of-two components in it. The simple add then mask was causing
things like 12000+ entry collision chains while most other entries have
between 0 and 3 entries each. This way seems to improve things.
