e2fsck: exit with exit status 0 if no errors were fixed
f_badorphan, f_journal: Update expect files to reflect the fact that new e2fsck's will move the .journal file to a hidden inode.
Add support for backing up the journal inode location in the superblock. E2fsck will automatically save the journal information in the superblock if it is not there already, and will use it if the journal inode appears to be corrupted. ext2fs_add_journal_inode() will also save the backup information, so that new filesystems created by mke2fs and filesystems that have journals added via tune2fs will also have journal location written to the superblock as well. Debugfs's logdump command has been enhanced so that it can use the journal information in the superblock.
