Macro stakker::stop

macro_rules! stop {
    ($cx:expr) => { ... };
}

Indicate successful termination of the actor

stop!(cx);

This just calls Cx::stop. It is included for symmetry with fail!.

As soon as the currently-running actor call finishes, the actor will be terminated. Actor state will be dropped, and any further calls to this actor will be discarded. The termination status is passed back to the StopCause handler provided when the actor was created.
