libocfs2: fix ocfs2_init_dir() to retain indexed flag
We were re-using the out of date 'cached inode' later in the function after
ocfs2_dx_dir_build() (which updates and writes out the inode internally).
As a result, ocfs2_init_dir() was accidentally clearing
OCFS2_INDEXED_DIR_FL. Fix this by refreshing the cache after the call to
ocfs2_dx_dir_build().

mkfs.ocfs2: create root and orphan directories as indexed
If the indexed dirs feature is enabled but the inline directories feature is
for some reason disabled, we'll create sub-optimal (non-indexed) root and
orphan directories. It's easy however at the end of mkfs.ocfs2 to simply
index these.

tunefs.ocfs2: move o2ne_add_tailers() into libocfs2ne.c
The prototype is already in libocfs2ne.h - this function is shared between
feature_metaecc.c and feature_indexed_dirs.c so it should be in a shared c
file as well.

dx_dirs: try to install dir trailers when enable indexed-dirs

ocfs2-tools does not install dir trailers and move the dir entries which

dx_dirs: fsck.ocfs2 support
This patch does a basic indexed dirs support in fsck.ocfs2.
During pass2, if a directory block is changed, and indexed dirs in
enabled, the indexed tree of this directory will be
truncate, then rebuild with the modified directory data. All the
modified directories' inode numbers are recored in a
rb-tree, when all directories get scanned, truncate and rebuild the
directories whose inode recorded in the rb-tree.

This patch adds more library support for indexed dirs,
- dx_root alloc/delete
- dx_leaf alloc/delete
- dx_root read/write
- dx_leaf read/write
- indexed tree insert/truncate
- dx_root extent tree operations
- indexed dir support in ocfs2_lookup_system_inode(),
ocfs2_init_dir(), ocfs2_link(), ocfs2_unlink(),
ocfs2_lookup().
With this patch, indexed dirs support in fsck.ocfs2 is possible.

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.

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.

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.
