    O2info: Add new running codes for '--filestat'.
    
    This patch not only tries to teach o2info to dump file's standard stat
    information, but also report some extended info such as extents, frag,
    holes, unwritten and shared space in clusters, which also was gained
    mainly by the help of new 'FS_IOC_FIEMAP' ioctl.

    O2info: Add new running codes for '--space-usage'.
    
    This patch tries to teach o2info to dump file's usage information on disk in
    terms of calculating its number of physical block, holes, reseverd/shared clusters
    with the help of new 'FS_IOC_FIEMAP' ioctl.

commit dd6f2cae76d69bea2382c2f45412bd1ae6187333
Author: Tristan Ye <tristan.ye at oracle.com>

    O2info: Make parts of o2info routines public.
    
    The idea here is to make parts of o2info operations public, a very original
    intention is driven by the thoughts of having some o2info functions sharable
    with debugfs.ocfs2, so that we'll be able to do 'freefrag'/'freeinode' things
    in debugfs as well.
    
    While such kind of o2info funcs were not that friendly/common enough to become
    sharable globally. that's the reason why we keep these under o2info in terms of
    libo2info instead of libocfs2.
    
    Further patches about 'freefrag' and 'freeinode' of o2info/debugfs.ocfs2 is going
    to be posted, being based on this patch.
