    ocfs2-tools/dx_dirs: Add tunefs.ocfs2 feature for indexed directories
    
    This only enables them for now. Disabling is a bit more involved, and will
    come later.

    ocfs2-tools/dx_dirs: mkfs.ocfs2 support
    
    This adds only basic support to mkfs.ocfs2 to write the seed fields used in
    directory indexing. The feature string 'indexed-dirs' is already there from
    a previous patch, so it is possible to create a new file system with the
    directory indexing feature turned on.
    
    Future improvements that are needed:
    
    - mkfs.ocfs2 should create the root directory and orphan dirs as indexed.
    - possibly also we want to do this for the system dir, but that might
      require some discussion.

    ocfs2-tools/dx_dirs: debugfs.ocfs2 support
    
    This adds a full set of functionality to debugfs.ocfs2 so that we can
    visualize and debug indexed directories. Aside from updates to other
    commands to dump newly added/used fields in old structures, we get the
    following debugfs.ocfs2 commands:
    
    dx_space - Show all entries in the free list
    dx_dump  - Show the directory index (including root block)
    dx_leaf  - Show a single directory index leaf block
    dx_root  - Show directory index root block, as well as any extent blocks for
               non-inline dx_roots.

    ocfs2-tools/dx_dirs: Add library support for directory indexing
    
    This patch updates ocs2_fs.h with the relevant directory indexing
    structures. Additionally, libocfs2/ is given swap functions for the new disk
    structures. The library also gets three new iteration functions:
    
    ocfs2_dx_entries_iterate() - to iterate all index entries in an inline, or
    external index.
    
    ocfs2_dx_frees_iterate() - an iterator for the dirblock free list.
    
    ocfs2_extent_iterate_dx_root() - iterate the extent blocks of an index tree.
    
    Caveats:
    
    Right now, this is all read-only. A major 'TODO' item is adding the
    appropriate API's to enable creation, deletion and various manipulation of
    the dx tree, as well as individual items.
    
    None of the other library code really knows about the directory index. This
    means that things like ocfs2_looup() is still using the old-style lookup via
    the unindexed dirent tree.
    
    We need to add support for the newly increased links_count maximum. This
    should probably be a seperate patch though.
