…es and listenable futures Implement bidirectional cancellation for `future` coroutine builder. This also: * Refactors JobListenableFuture infrastructure so it can be reused in CoroutineScope.future and Deferred.asListenableFuture; * Provides more descriptive `toString` implementation for the returned Future; * Fixes stack traces in thrown exception, so it includes call to get() that triggered the exception to be thrown; * Hides ListenableFuture.asDeferred return type, so it can't be casted to CompletableDeferred; * Adds more tests to cover fixed corner cases; * Improves documentation; * Suppresses annoying warnings in tests.

* Replace `Result` with `Cancelled` to save an allocation on successful completion. * Add a test to show that `CancellationException` is never passed to `CoroutineExceptionHandler`. * Explicitly specify return types. * Use @JvmField on "package-private" property to not generate an accessor.
