This series adds two new helpers to easily read from and write to bio_bvecs,
and switches the loop driver and target file backend to use it.

Using bio_vecs directly avoids the need to kmap individual elements in
the callers, which is epecially important in the target driver, and also
gets rid of the horrible splice code abuse hack in the loop driver.
