    ctr/libgfdb: Performance enhancer for unlink/create/rename/link fops

    1) ctr_link_consistency option for ctr xaltor is provided so that
       the user can choose to switch it on or off.
       /* For link consistency we do a double update i.e mark the link
       * during the wind and during the unwind we update/delete the link.
       * This has a performance hit. We give a choice here whether we need
       * link consistency to be spoton or not using link_consistency flag.
       * This will have only one link update */

    2) In delete the wind time recording is moved to unwind path.
       /* Special performance case:
       * Updating wind time in unwind for delete. This is done here
       * as in the wind path we will not know whether its the last
       * link or not. For a last link there is not use to update any
       * wind or unwind time!*/
