* SuspendFunction[01] interfaces removed, moved to RestrictedContinuationImpl
* validateContext introduced to check restricted coroutines
* Distinguish SuspendLambda as being lambda/coroutine and provide a separate
toString implementation (draft) in its coroutine incarnation.
* SuccessOrFailure inline class is introduced
* Continuation.resumeWith(SuccessOrFailure)
* createCoroutineUnintercepted
* [Restricted]ContinuationImpl as named suspending function base
* [Restricted]SuspendLambda as suspending lambda base
* SuspendFunction[01] interfaces for efficient createCoroutine
* Serializable coroutine classes
Copy everything from kotlin.coroutines.experimental to
kotlin.coroutines. The latter is separate source set to be packed into
separate kotlin-stdlib-coroutines.jar
