38760e2432 ocfs2: Rename cleanups
ocfs2_rename() does direct manipulation of the dirent it's gotten back from
a directory search. Wrap this manipulation inside of a function so that we
can transparently change directory update behavior in the future. As an
added bonus, this gets rid of an ugly macro.

be94d11704 ocfs2: Provide convenience function for ino lookup
A couple paths which needed to just match a parent dir + name pair to an
inode number were a bit messy because they had to deal with
ocfs2_find_files_on_disk() which returns a larger number of values. Provide
a convenience function, ocfs2_lookup_ino_from_name() which internalizes all
the extra accounting.

0bfbbf62a8 ocfs2: Implement ocfs2_empty_dir() as a caller of ocfs2_dir_foreach()
We can preserve the behavior of ocfs2_empty_dir(), while getting rid of the
open coded directory walk by just providing a smart filldir callback. This
also automatically gets to use the dir readahead code, though in this case
any advantage is minor at best.

5eae5b96fc ocfs2: Remove open coded readdir()
ocfs2_queue_orphans() has an open coded readdir loop which can easily just
use a directory accessor function.

316f4b9f98 ocfs2: Move directory manipulation code into dir.c
The code for adding, removing, deleting directory entries was splattered all
over namei.c. I'd rather have this all centralized, so that it's easier to
make changes for inline dir data, and eventually indexed directories.

None of the code in any of the functions was changed. I only removed the
static keyword from some prototypes so that they could be exported.

1fabe1481f ocfs2: Remove struct ocfs2_journal_handle in favor of handle_t
This is mostly a search and replace as ocfs2_journal_handle is now no more
than a container for a handle_t pointer.

ocfs2_commit_trans() becomes very straight forward, and we remove some out
of date comments / code.
