v3->v4:
1.address Atsushi Kumagai's comments about using divideup
v2->v3:
1.remove the filtering for incomplete block (previous second pass) and
adjust
relevant codes
2.address HATAYAMA's comments about coding style
v1->v2:
1.use splitblock instead of block
2.add restriction (align to the page size) to splitblock size
3.adjust the position of prepare_splitblock_table and check the return
code
4.use --splitblock-size to specify splitblock size and modify the
print_info.c
the v2 test result is:
