sdong 5cc9adf5ba WriteBatchWithIndex's Iterator bug of SeekToFirst() and SeekToLast() ... Summary: WriteBatchWithIndex's iterator's SeekToFirst() and SeekToLast() use offset=0 to indicate it is smaller than all the keys, which is wrong. offset=0 will decode a key "" (the header decodes like that). It could be larger than other keys in non-default comparators. Fix it by using a special flag of offset to indicate searching to the beginning of the CF. Test Plan: Add a unit test that used to fail. Also, add some more tests to related cases, though they don't fail for now.
