177: implement DoubleEndedStream r=yoshuawuyts a=yoshuawuyts
Ref #129. This is the most basic version of the `DoubleEndedStream` trait. Because there is no counterpart in `futures-rs` we allow this to be implementable (not sure if we should though?).
This is not a high-priority trait to implement, with probably the most useful addition being the blanket impl over [`std::iter::Fuse`](https://doc.rust-lang.org/std/iter/struct.Fuse.html) (where we should have a `Fuse` counterpart for `Stream` also).
So I'm taking this one step at the time, and this PR introduces just the bare minimum to get things working. Thanks!

184: housekeeping after 145 r=yoshuawuyts a=montekki
Now that #145 is merged combinators can follow.
1. All combinators taking `&mut self` should imply `Self: Pin`.
2. Trait bounds are to `Stream`
3. Cleans up docs and `Debug` derives.

189: links the timeout docs to each other r=yoshuawuyts a=yoshuawuyts
Was talking in chat about futures timeouts, and apparently folks missed we had two different timeout functions. This links them to each other so if you find one, you also become aware of the other. Thanks!

188: Refactor the networking driver r=stjepang a=stjepang
This is a big cleanup that simplifes the layer between mio and our networking driver. The `Watcher` API was pretty much entirely designed by @yoshuawuyts.
Fixes#185

145: Add Stream::poll_next r=stjepang a=stjepang
Adding `poll_next` to the `Stream` trait will simplify #125.
After a discussion with @yoshuawuyts and @withoutboats, we became confident that the `Stream` trait of the future will never solely rely on `async fn next()` and will always have to rely on `fn poll_next()`.
This PR now makes our `Stream` trait implementable by end users.
I also made a few adjustments around pinning to `all()` and `any()` combinators since they take a `&mut self`, which implies `Self: Unpin`. A rule of thumb is that if a method takes a `&mut self` and then pins `self`, we *have to* require `Self: Unpin`.

163: adds stream::filter_map combinator r=yoshuawuyts a=montekki
Implements a `flat_map` combinator. Currently the same about `ret!` as in #162 .
Also the naming should probably be `FilterMapStream`, but in that case `Take` stream should also change it's name i guess.

168: Cache cargo artifacts r=yoshuawuyts a=stjepang
Supersedes #114
This does not cache `~/.cargo/registry` because it's too big.
