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!*/
