This adds simpler versions of bvec_iter_advance() and bio_advance_iter()
(i.e. *_single()), that are faster but work with the restriction that
@bytes shouldn't be more than available in the current bvec segment.

That covers most of bvec/bio iteration/foreach, that are massively
inlined, and thus also nicely shrinks binary.

Others non core-block users might be updated on case by case basis
(if applicable) after the change is merged.

Applied, thanks.
