224: Re-export IO traits from futures r=stjepang a=stjepang
Sorry for the big PR!
Instead of providing our own traits `async_std::io::{Read, Write, Seek, BufRead}`, we now re-export `futures::io::{AsyncRead, AsyncWrite, AsyncSeek, AsyncRead}`. While re-exporting we rename them to strip away the "Async" prefix.
The documentation will display the contents of the original traits from the `futures` crate together with our own extension methods. There's a note in the docs saying the extenion methods become available only when `async_std::prelude::*` is imported.
Our extension traits are re-exported into the prelude, but are marked with `#[doc(hidden)]` so they're completely invisible to users.
The benefit of this is that people can now implement traits from `async_std::io` for their types and stay compatible with `futures`. This will also simplify some trait bounds in our APIs - for example, things like `where Self: futures_io::AsyncRead`.
At the same time, I cleaned up some trait bounds in our stream interfaces, but haven't otherwise fiddled with them much.
I intend to follow up with another PR doing the same change for `Stream` so that we re-export the stream trait from `futures`.
