Introduce a tokio-sync crate containing useful synchronization primitives for programs written using Tokio. The initial release contains: * An mpsc channel * A oneshot channel * A semaphore implementation * An `AtomicTask` primitive. The `oneshot` and `mpsc` channels are new implementations providing improved performance characteristics. In some benchmarks, the new mpsc channel shows up to 7x improvement over the version provided by the `futures` crate. Unfortunately, the `oneshot` implementation only provides a slight performance improvement as it is mostly limited by the `futures` 0.1 task system. Once updated to the `std` version of `Future` (currently nightly only), much greater performance improvements should be achievable by `oneshot`. Additionally, he implementations provided here are checked using [Loom](http://github.com/carllerche/loom/), which provides greater confidence of correctness.
