fswreck: Add corruption for DUP_CLUSTERS_ADD_REFCOUNT.
DUP_CLUSTERS_ADD_REFCOUNT is used to improve the process
we handle duplicated clusters. So we can just corrupt
the root extent block so that all the refcounted clusters
will be treated as duplicate clusters.

fsck.ocfs2: User refcount to handle dup_clusters.
In the old times, when we meet with a duplicate
cluster, we clone the 2 files. It is OK but it
is also time-consuming and space-consuming.
Now With reflink, we will try to create refcount
tree first for these files and add refcount rec
so that we avoid duplicating inodes.

fsck.ocfs2: Store refcounted clusters.
As for the leaf extent record, we generize a function
mark_rec_alloc_func in case they are allocated from the
global_bitmap. As for refcounted clusters, we store them
to a rb-tree so that we can check them later.
For the leaf refcount rec, they are allocated from extent
alloc, so no need to set them.

We check refcount tree if an inode have one. But there
are many inodes sharing the same tree, and we only need

fsck.ocfs2: Make extent list check prompt more generic.

We pass an owner instead like we do in the kernel.

Note from Tao Ma:
The original form is from
http://oss.oracle.com/pipermail/ocfs2-tools-devel/2009-October/002279.html.
I just copied the value tree here and I also changed the
prototype for value_tree init. We have to pass xattr write
function to the tree since the xattr value can be in inode,
block or bucket.

libocfs2: Add xattr iteration process.
In some other tools(tunefs.ocfs2 and fsck.ocfs2), we need
to iterate xattr many times, so we'd better have an iteration
process for xattr.
I have taken some reference from Tiger's intial draft.

Thank tiger for it.
It has changed a lot in this version.

tunefs.ocfs2: Add refcount feature disable/enable.
The enable part is very simple.
As to disable refcount feature, it will use ocfs2_refcount_cow
to CoW the refcounted clusters.
This patch only for the inode extents, the xattr part will be
implemented in the later patch.

debugfs.ocfs2: Dump refcount trees
debugfs.ocfs2 gains the 'refcount' command. This will dump a refcount
tree including its extents. If passed an inode specification, it will
dump the refcount tree associated with that inode. If it is passed the
refcount block directly (surrounded by angle brackets, of course), it
will just read the refcount block.

libocfs2: Add CoW support.
This patch try CoW support for a refcounted record.
the whole process will be:
1. Calculate how many clusters we need to CoW and where we start.
Extents that are not completely encompassed by the write will
be broken on 1MB boundaries.
2. Do CoW for the clusters.
3. Change the b-tree structure with the new allocated clusters.
If the old extent has refcount=1, just remove the refcounted flag
and it is OK.

ocfs2: Decrement refcount when truncating refcounted extents.
Add 'Decrement refcount for delete' in to the normal truncate
process. So for a refcounted extent record, call refcount rec
decrementation instead of cluster free.
Note:
Some xattr truncate functions have to be changed to pass
inode number into truncate so that we can find the proper
refcount tree.
