nilfs2: insert checkpoint number in segment summary header
This adds a field to record the latest checkpoint number in the nilfs_segment_summary structure. This will help to recover the latest checkpoint number from logs on disk. This field is intended for crucial cases in which super blocks have lost pointer to the latest log. Even though this will change the disk format, both backward and forward compatibility is preserved by a size field prepared in the segment summary header.
