Remove qualifying path from Read and Write 

There is no advantage in having `io::Read` as opposed to `Read` and
importing the trait. It is surprising that we do so.

Remove `io::` path from `io::Read` and `io::Write`. Some docs keep the
path, leave them as is. Add import `use io::{Read, Write}`.

Refactor only, no logic changes.
