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.

The current build system fails to `make distcheck` correctly
for two reasons: 1) Some header files are not listed in the
source files for fsck.f2fs and mkfs.f2fs, and so don't make it
into the dist tarball. 2) By setting a default prefix in
configure.ac, the mock install doesn't add the correct prefix
and instead tries to install directly to the file system.
This patch corrects those problems and also adds an autogen.sh
script for convenience.
