Eric Sandeen fb6627a3fb libext2fs: Fix byte-swap logic for i_block[] in inodes with extents

Eric Sandeen 82e541885e Fix ext2fs_swap_inode_full() for in-inode xattrs on big-endian machines
After the fix for resize2fs's inode mover losing in-inode
extended attributes, the regression test I wrote caught
that the attrs were still getting lost on powerpc.

Looks like the problem is that ext2fs_swap_inode_full()
isn't paying attention to whether or not the EA magic is
in hostorder, so it's not recognized (and not swapped)
on BE machines.  Patch below seems to fix it.

Yay for regression tests.  ;)

Theodore Ts'o 4ce3b77480 Don't byte swap extents information in the inode
Responsibility for byte swapping the extents information rests with
the low-level extent code, which translates the on-disk extents
information to the abstract extent format.  The on-disk format will
eventually get more complicated, in order to add support for 64-bit
block numbers, bit-compressed extents, etc.  So to avoid needing to
expose all of that complexity in swapfs.c, the in-memory contents of
i_blocks will not be byte-swapped and will be identical to the on-disk
format.

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 f5fa20078b Add support for EXT2_FEATURE_COMPAT_LAZY_BG
This feature is initially intended for testing purposes; it allows an
ext2/ext3 developer to create very large filesystems using sparse files
where most of the block groups are not initialized and so do not require
much disk space.  Eventually it could be used as a way of speeding up
mke2fs and e2fsck for large filesystem, but that would be best done by 
adding an RO_COMPAT extension to the filesystem to allow the inode table
to be lazily initialized on a per-block basis, instead of being entirely initialized
or entirely unused on a per-blockgroup basis.
