This patch is an intial implementation of the Tokio runtime. The Tokio runtime provides an out of the box configuration for running I/O heavy asynchronous applications. As of now, the Tokio runtime is a combination of a work-stealing thread pool as well as a background reactor to drive I/O resources. This patch also includes tokio-executor, a hopefully short lived crate that is based on the futures 0.2 executor RFC. * Implement `Park` for `Reactor` This enables the reactor to be used as the thread parker for executors. This also adds an `Error` component to `Park`. With this change, a `Reactor` and a `CurrentThread` can be combined to achieve the capabilities of tokio-core.
