vnode numbers are AFS's equivalent of inode numbers. Since they're one per
file, they could be the object filename.
Probably there would have to be a table of {vnode,latest_uniquifier} as the
uniquifier must still go up even if the vnode is unused for a while, so there
could also be a table of {vnode,btrfs_file}.
