nilfs2: fiemap support
This adds fiemap to nilfs. Two new functions, nilfs_fiemap and nilfs_find_uncommitted_extent are added. nilfs_fiemap() implements the fiemap inode operation, and nilfs_find_uncommitted_extent() helps to get a range of data blocks whose physical location has not been determined. nilfs_fiemap() collects extent information by looping through nilfs_bmap_lookup_contig and nilfs_find_uncommitted_extent routines.
