the extended region of nilfs_mdt_info struct. The struct
nilfs_ifile_info defines the extended on memory structure of ifile.

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.
