nilfs2: integrated block mapping
This adds structures and operations for the block mapping (bmap for
short). NILFS2 uses direct mappings for short files or B-tree based
mappings for longer files.
Every on-disk data block is held with inodes and managed through this
block mapping. The nilfs_bmap structure and a set of functions here
provide this capability to the NILFS2 inode.
