Merge #914

914: Make preadv take immutable slice of IoVecs r=asomers a=farnoy

fixes #913

I filled in the CHANGELOG, but I see that it usually links to PRs and not issues, do you want me to change it or remove and leave for you to describe?

This change seems to be strictly backwards-compatible, I didn't have to change the test for it to work.
