    Mandy Kirkconnell authored
    code to prepare for an upcoming mod which will introduce multi-level
    in-core extent allocations. Although the in-core extent management is
    using a new code path in this mod, the functionality remains the same. 
    Major changes include:	- Introduce 10 new subroutines which re-orgainze
    the existing code but	do NOT change functionality:	    
    xfs_iext_get_ext()	   xfs_iext_insert()	     xfs_iext_add()	  
     xfs_iext_remove()	   xfs_iext_remove_inline()	   
    xfs_iext_remove_direct()	 xfs_iext_realloc_direct()	  
    xfs_iext_direct_to_inline()	    xfs_iext_inline_to_direct()        
    xfs_iext_destroy() - Remove 2 subroutines (functionality moved to new
    subroutines above):	    xfs_iext_realloc() -replaced by xfs_iext_add()
    and xfs_iext_remove()	      xfs_bmap_insert_exlist() - replaced by
    xfs_iext_insert()	  xfs_bmap_delete_exlist() - replaced by
    xfs_iext_remove() - Replace all hard-coded (indexed) extent assignments
    with a call to	 xfs_iext_get_ext() - Replace all extent record pointer
    arithmetic (ep++, ep--, base + lastx,..)   with calls to
    xfs_iext_get_ext() - Update comments to remove the idea of a single
    "extent list" and   introduce "extent record" terminology instead
