HAMMER VFS - version 2 work - move directory entries to inode localization
* Set version 2 features. Directories created in a version 2 HAMMER
filesystem place their directory entries in the B-Tree's inode localization
space instead of the general space. Pre-existing directories continue
to use the old scheme.
* Amost doubles directory lookup / find / ls performance in effected
directories. However, at the moment the B-Tree must be reblocked before
the gains are seen.
