defrag.f2fs: introduce defragmentation tool
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.
