nilfs2: separate constructor of metadata files
This will displace nilfs_mdt_new() constructor with individual metadata file constructors like nilfs_dat_new(), new_sufile_new(), nilfs_cpfile_new(), and nilfs_ifile_new(). This makes it possible for each metadata file to have own intialization code. Signed-off-by: Ryusuke Konishi <konishi.ryusuke@lab.ntt.co.jp>
