nilfs2: B-tree based block mapping
This adds declarations and functions of NILFS2 B-tree. Two variants are integrated in the NILFS2 B-tree. The B-tree for the most files points to the child nodes or data blocks with virtual block addresses, whereas the B-tree of the DAT uses actual block addresses.
