    debugfs.ocfs2: Correct range check of ocfs2_read_backup_super()
    
    debugfs.ocfs2 is unable to access the backup at block[0] of the offset array.
    This is because of the incorrect range check and evaluation of block offset.
    Correct the range check and usage of the function.
    
    Not sure if I am changing the convention on how you perceive the block indexes
    here though. In any case, I am following the fsck.ocfs2 user interface
    [1,sbnum], and internally [0,sbnum).

    debugfs.ocfs2: Swap to little-endian before computing metaecc
    
    debugfs.ocfs2 disables metaecc checks while reading the blocks so as to allow
    it to show blocks that have incorrect metaecc. Such blocks are shown with their
    current and expected metaecc values.
    
    To do that, it has to compute it manually. But it encounters a problem in that
    the metadata blocks have already been swapped to the cpu format in the read
    routine. The metaecc compute only works in the little-endian format.
    
    This patch teaches debugfs to detect all metadata blocks and swap their
    elements to the little endian format before computing the metaecc.

    libocfs2: Define FS_IOC_FIEMAP
    
    Add definition of FS_IOC_FIEMAP to allow it to build on older build environments.
