xfsprogs: sync kernel inode cluster size refactor code

Hi Folks,

This patch series sync up the code differences between kernel and user space for xfs_icluster_size_fsb() relevant changes, i.e,
http://oss.sgi.com/archives/xfs/2013-12/msg00499.html

Most patches are similar to the kernel part except we have xfs_bulkstat() and xfs_ifree_cluster() at kernel space but they are not presented at user space.

Hi Folks,

http://oss.sgi.com/archives/xfs/2013-12/msg00499.html

Most patches are similar to the kernel part except we have xfs_bulkstat() and xfs_ifree_cluster() at kernel space but they are not presented at user space.

Given that we need to do a wholesale resync of libxfs to the kernel code, I'm not sure it makes sense to do little bits out of order. it just makes syncing all the other prior changes harder because it causes patch conflicts...

I'm planning that this is the first thing that we need to do after the 3.2.0 release before anything else....
