dd1ba078fa Unify version and date management
Patch 1:
 Now we have two different versions that produce different superblocks/
 filesystems with the same version info. Major/minor version in the sb
 should reflect the version of the tool creating the filesystem. This
 patch will ensure that the version entered in the file VERSION will
 be used consistently throughout the code.

Patch 2:
 In order to simplify the maintenance with a new release the date
 in F2FS_TOOLS_DATE is now take from the last commit in git. Thus,
 git is needed to run autoconf. However, git is not needed for the
 simple build procedure, ./configure && make, that should be the
 only things needed to build the tool from a tar.gz package.

 Pros & Cons:
  [+] Automated
  [+] True
  [-] Git needed to run autoreconf

Change log by Jaegeuk from the initial patch-set:

- Merge two patches into one
 : Eliminate the intermediate state having version.h and VERSION.

- Remove the Git dependency which is one of Cons
 : If there is no git tree, just use DATE described in VERSION.

- Minor coding style

 Pros & Cons:
  [+] Automated
  [+] True
  [+] No Git dependency

c0f2b9065c Ignore configure.lineno
Autotools may spit out the file configure.lineno, which git
should ignore as well.

c6ff6d09de Bug fix: Fix overflow when calculating block address
This patch fixes the bug as follows.
"I'm trying to roll out f2fs on top of SDHC card and faced with following
issue - after mounting card I cannot read device root entry. It returns
-1 EINVAL (entry too big).
getdents(3, /* 1 entries */, 32768)     = 24
getdents(3, 0x1082c88, 32768)           = -1 EINVAL (Invalid argument)"
		reported by Ruslan N. Marchenko [me@ruff.mobi].

This bug is easily reproducible and I couldn't have checked the mount
entry cautiously.
Due to the bug, f2fs couldn't get default dentries, . and .., in the root
directory. In the case of other newly created directories, that's fine.

The problem was the overflow during casting variables while calculating the
block address of the root dentry block.
In order to avoid that, I simply split the equation under consideration of
the casting issue.

4ed75df379 Bug fix: store superblocks with correct offset
There are two superblock writes in mkfs.f2fs.

offset: 0     1024                 4095      5119                 8191
        |------> 1'st superblock ----|--------> 2'nd superblock ----|

Therefore, each superblocks has 1024 byte-size offset.

22a75edd47 Enhancement: shorten umount time
When f2fs is unmounted cleanly, it stores active summmary blocks of nodes in the
checkpoint pack in order to avoid reconstruct all of them at the later mount
time. Previously, mkfs didn't prepare that, which is why the initial mount time
is so huge.

99b7439340 Enhancement: add uuid
"Usually, it is used 128-bits UUID for serial number. Why do you use
__le32 as volume_serial_number?"
>From Vyacheslav Dubeyko.

I added an uuid facility for the serial number.
And sync with kernel/include/linux/f2fs_fs.h.

b5af7953f8 Enhancement: add i_atime and i_generation
"You appear to have dropped i_btime - no big deal, you weren't using it anyway.
However if you ever want to support NFS export you will need some value which
is assigned when the inode is allocated and never changed until it is
de-allocated.  This is used to detect when an NFS file-handle refers to a
previous incarnation of an inode and so should be rejected as STALE.
i_btime could have possibly provided this, but not any more.  You might want
to add something back.
ext3 uses "i_generation" and has an 's_next_generation' in the superblock to
ensure that each new inode gets a new generation number.

You've also dropped i_atime.  I can certainly understand the desire to do
that, but I wonder if it is entirely wise.  There are some use-cases where
i_mtime is a poor substitute.

Also 'current_depth' looks a little odd without a 'i_' prefix.  It wouldn't
hurt to have a comment noting that it is for directories."
