libocfs2, mkfs.ocfs2: Add checksums and ecc to dirblocks.
Now the functions to read and write dirblocks can compute checksums.

commit e5b47ceced03c59401c10e5af2e9d3b522897619
Author: Joel Becker <joel.becker at oracle.com>
Date: Thu Dec 18 02:19:55 2008 -0800
mkfs.ocfs2: Write directory trailers when necessary.
Add the code to put trailers on dirblocks when they are created in mkfs.
This includes a little convenience routine, fill_fake_fs(), that allows
us to use simple functions on a fake ocfs2_filesys created from State.

libocfs2: Handle dir trailer fields at dirblock read/write.
Swap the inode and rec_len fields of the dir trailer when we read and
write a dirblock. Check the dir trailer signature if we're supposed to.

commit 33c63d5a9bf453fbcf76629d267489d6c21fef22

Date: Wed Dec 17 17:53:27 2008 -0800
libocfs2: Initialize dirblock trailers when creating new dirblocks.
libocfs2 creates new dirblocks in three places:
- non-inline mkdir
- expanding inline to a dirblock
- adding a new dirblock
All places now initialize a trailer if necessary.

commit b650e25d53dee3df6794f8d1d7ce6533a14d7de2

Date: Wed Dec 17 17:32:22 2008 -0800
fsck.ocfs2: Add checking of directory trailers.
If we have trailers, fsck needs to know about them.
In pass2, we don't treat the trailer of a directory block as a regular
dirent. We fix the trailer's compatibility fields if they are broken.

commit 6b68bfe996ae6f06fc14942b9d525274a89e4241
Author: Joel Becker <joel.becker at oracle.com>
Date: Wed Dec 17 16:53:56 2008 -0800
libocfs2: Skip dir trailers in our iterators.
The ocfs2_dir_iterate*() and ocfs2_dir_scan*() functions need to skip
dirblock trailers. ocfs2_dir_iterate*() can be passed
OCFS2_DIRENT_FLAG_INCLUDE_TRAILER if you really want to see it.

libocfs2: Pass the dinode to ocfs2_read/write_dir_block().
Future code will need to look at the dinode when reading and writing
dirblocks, so let's pass it in.

libocfs2: Bring ocfs2_fs.h from the kernel.
Bring in the latest ocfs2_fs.h from the kernel. This includes the
quota, xattr, and dir trailer structures.
The only changes from the kernel:
- Remove XATTR and QUOTA from the list of supported features.
- Remove the quota system files from the system inode list.

libocfs2: Cache code bits in parity calculation
The parity calculation has to convert a data buffer bit offset into a
code buffer bit offset. By caching the difference between those
offsets, we can make the calculation faster. It starts from a more
recent place.

libocfs2: Shrink the usage of the ocfs2_hamming_encode() function.
Take the hand-coded xor and just use xor on the word. Start
calc_code_bit() at a good approximation.

libocfs2: Change ocfs2_open()'s csum check to match the kernel.
The ocfs2_open() code can't sanely swap a superblock that isn't a valid
superblock - it walks off the end.
Let's do what the kernel does - validate the signature first, then check
the ecc. It means that ecc can't fix the signature, but that's a tiny
little window fixed by backup supers.

libocfs2: ECC needs the correct bitcount.
I was passing 'blocksize' to the hamming code functions. But they work
on bits, not bytes, so they were eccing the first 1/8 of the block.
Whoops!

blockcheck: Properly handle back checksums in openfs.
read_super() can return ET_IO for back checksums. This will always
happen when we're scanning for the superblock, so ocfs2_open() needs to
