When moving data or node blocks, it changes current segment information
dynamtically. Meanwhile, its journal entry space is recovered by old
stale data.
This patch makes sure that its journal space is zeroed out.

Currently, directory should not have any extent cache entry.
Otherwise, fsck.f2fs will trigger a false-alarmed report.

We reserved one segment for NAT region at least, so when formatting
fs, calculated maximum size of left space in CP page should be:
CHECKSUM_OFFSET - sizeof(struct f2fs_checkpoint) + 1 - 64 (size of
reserved NAT bitmap).
Fix the incorrect calculated size to avoid potential overflow bug here.

This tool tries to move the valid blocks ranging from blkaddr to blkaddr + len
to targeted blkaddr with a direction like expand or shrink.
The option includes:
-d debug level [default:0]
-s start block address [default: main_blkaddr]
-l length [default:512 (2MB)]
-t target block address [default: main_blkaddr + 2MB]
-i set direction as shrink [default: expand]
For example,
# defrag.f2fs -s 0x100 -l 0x10 -t 0x4000 /dev/sdb1
This will move data blocks between 0x100 and 0x110 to the right side of
0x4000 space.

This patch gives the version info for two libraries.
mkfs/libf2fs_format.la
lib/libf2fs.la
The versioning rule should be:
1. Start with version information of '0:0:0' for each libtool library.
2. Update the version information only immediately before a public release of
your software. More frequent updates are unnecessary, and only guarantee
that the current interface number gets larger faster.
2. If the library source code has changed at all since the last update, then
increment revision (c:r:a) becomes (c:r+1:a).
3. If any interfaces have been added, removed, or changed since the last update,
increment current, and set revision to 0.
4. If any interfaces have been added since the last public release, then
increment age.
5. If any interfaces have been removed or changed since the last public release,
then set age to 0.

libf2fs_fmt is compiled from the same sources of mkfs.f2fs. This library is
required by libf2fs_utils and fastboot from the Android Open Source Project
and we believe the Android SDK maintainers from Debian will greatly benefit
from this change.

If there are many obsolete blocks written by previous usage, we can recover
wrong blocks with them.
So, mkfs should discard whole wrong information correctly by removing possible
same checkpoint versions.

Previously, check_sit_types didn't handle different numbers of active logs and
