Migrate to Kotlin 1.3 coroutines, drop experimental from package

* Features based on version 0.30.0
* Uses Kotlin version 1.3.0-rc-57
* Uses Kotlin/Native version 0.9.2
* Uses AtomicFu 0.11.9-eap13
* Replace SuccessOrFailure with Result
* Replace buildSequence and buildIterator with sequence and iterator
* Apply @BuilderInference on all builders (including extension methods to workaround inference bug)

   * All coroutine builders are now extensions on `CoroutineScope` and inherit its `coroutineContext`. Standalone builders are deprecated.
   * As a consequence, all nested coroutines launched via builders now automatically establish parent-child relationship and inherit `CoroutineDispatcher`.
   * All coroutine builders use `Dispatchers.Default` by default if `CoroutineInterceptor` is not present in their context.
