Replace the current mess of dir2 headers with just three that have a clear purpose: - xfs_dir2_format.h for all format definitions, including the inline helpers to access our variable size structures - xfs_dir2_priv.h for all prototypes that are internal to the dir2 code and not needed by anything outside of the directory code. For this purpose xfs_da_btree.c, and phase6.c in xfs_repair are considered part of the directory code. - xfs_dir2.h for the public interface to the directory code In addition to the reshuffle I have also update the comments to not only match the new file structure, but also to describe the directory format better.
