Theodore Ts'o 695706ca21 e2fsck: Interpret negative blkcount in file system problem reports
Non-expert users get confused when they see messages like this:

Illegal block #-1 (2291965952) in inode 176. CLEARED.

So change it to be something a little bit more understandable:

Illegal indirect block (2291965952) in inode 176.  CLEARED.

Theodore Ts'o 7dca4c88f1 e2fsck: When repacking directories, leave slack space for more efficiency
If the directory is packed with no slack space, as soon as any new
directory entries are added, leaf nodes end up getting split and
directory ends up getting very inefficient.

Theodore Ts'o 2a60480627 e2fsck: Use "Clear Htree" instead of "Clear" when the Htree is corrupt
Change the prompt so it is clear to the user that e2fsck will be
clearing the htree information, not the directory inode itself, when
the htree information has proven to be corrupt.

Theodore Ts'o f77704e416 Add directory hashed signed/unsigned hint to superblock
The e2fsprogs and kernel implementation of directory hash tree has a
bug which causes the implementation to be dependent on whether
characters are signed or unsigned.  Platforms such as the PowerPC,
Arm, and S/390 have signed characters by default, which means that
hash directories on those systems are incompatible with hash
directories on other systems, such as the x86.

To fix this we add a new flags field to the superblock, and define two
new bits in that field to indicate whether or not the directory should
be signed or unsigned.  If the bits are not set, e2fsck and fixed
kernels will set them to the signed/unsigned value of the currently
running platform, and then respect those bits when calculating the
directory hash.  This allows compatibility with current filesystems,
as well as allowing cross-architectural compatibility.

Theodore Ts'o 7ae1983a23 Clean up e2fsck problem description messages for typo's and to make them
easier to understand (sorry, translators).

Add new @m (multiply-claimed) and @n (invalid) expansions for e2fsck
problem descriptions.

Add Dutch translation, and update French translation.

Add an explanation of how the @-expansion and %-exapansion works in 
e2fsck/problem.c to make life easier for the translators.

Synchronize and update po files.

Theodore Ts'o 33db8f80f2 Remove support for --enable-clear-htree; this was
only needed during the early development of the htree patch.

Theodore Ts'o a435ec3449 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.

The debugfs man page has been improved to more fully describe the
logdump command.

Added two new functions, ext2fs_file_open2() and 
ext2fs_inode_io_intern2() which take a pointer to an inode structure;
this is needed so that e2fsck and debugfs can synthesize a
fake journal inode and use it to access the journal.

Theodore Ts'o ad4fa46604 Avoid counting directory entries during a directory salvage.
Add additional checks to HTREE directories.  We now check the count
and limit fields in the htree header, as well as assuring that the
hash table in each interior node is in ascending order.  We also
check to make sure all leaf nodes are have the expected depth in 
the tree.

Updated test cases to deal with all of the above.

code to make it more maintainable, etc.)
