It cleans up the docs to have the futures in their own modules as users
are unlikely to look at them. Also matches the pattern used in tower
https://docs.rs/tower/0.4.8/tower/util/future/index.html.
Added re-exports to the old locations so its not a breaking change.

This breaks up `extract.rs` into several smaller submodules. The public
API remains the same.
This is done in prep for adding more tests to extractors which would get
messy if they were all in the same file.
Example usage:
```rust
use axum::{prelude::*, sse::{sse, Event, KeepAlive}};
use tokio_stream::StreamExt as _;
use futures::stream::{self, Stream};
use std::{
time::Duration,
convert::Infallible,
};
let app = route("/sse", sse(make_stream).keep_alive(KeepAlive::default()));
async fn make_stream(
// you can also put extractors here
) -> Result<impl Stream<Item = Result<Event, Infallible>>, Infallible> {
// A `Stream` that repeats an event every second
let stream = stream::repeat_with(|| Event::default().data("hi!"))
.map(Ok)
.throttle(Duration::from_secs(1));
Ok(stream)
}
```
Implementation is based on [warp's](https://github.com/seanmonstar/warp/blob/master/src/filters/sse.rs)
Axum expected the `Connection` header to be _exactly_ `upgrade`. Turns
out thats a bit too strict as this didn't work in Firefox.
Turns out `Connection` just has to contain `upgrade`. At least that is
what [warp does](https://github.com/seanmonstar/warp/blob/master/src/filters/ws.rs#L46).
Fixes https://github.com/tokio-rs/axum/issues/43
With this you can get the remote address like so:
```rust
use axum::{prelude::*, extract::ConnectInfo};
use std::net::SocketAddr;
let app = route("/", get(handler));
async fn handler(ConnectInfo(addr): ConnectInfo<SocketAddr>) -> String {
format!("Hello {}", addr)
}
// Starting the app with `into_make_service_with_connect_info` is required
// for `ConnectInfo` to work.
let make_svc = app.into_make_service_with_connect_info::<SocketAddr, _>();
hyper::Server::bind(&"0.0.0.0:3000".parse().unwrap())
.serve(make_svc)
.await
.expect("server failed");
```
This API is fully generic and supports whatever transport layer you're using with Hyper. I've updated the unix domain socket example to extract `peer_creds` and `peer_addr`.
