xfs: introduce the xfs_iext_cursor abstraction
Add a new xfs_iext_cursor structure to hide the direct extent map index manipulations. In addition to the existing lookup/get/insert/ remove and update routines new primitives to get the first and last extent cursor, as well as moving up and down by one extent are provided. Also new are convenience to increment/decrement the cursor and retreive the new extent, as well as to peek into the previous/next extent without updating the cursor and last but not least a macro to iterate over all extents in a fork.
