* BalancingPool companion
* ask
* problem filter for ActorDSL
* event bus
* exclude hasSubscriptions
* exclude some problems in testkit
* boundAddress and addressFromSocketAddress
* Pool nrOfInstances
* PromiseActorRef
* check with 2.3.9
* migration guide note
* explicit exclude of final class problems
* in the end TestKitBase eagerly initialize the ActorSystem and
to avoid the need for using lazy val tricks I changed the trait
to abstract class with config constructor parameter
* and don't show AkkaSpec in doc code

* also improved fault handling in various places (bugs found)
* and manually triggered Update must be distinguished from scheduled
auto updates, otherwise manual Update will schedule extra auto updates
This is the first step towards more type-safety in Actor interactions,
comprising:
* generic ActorRef[T] that only accepts T messages
* generic ActorSystem[T] extends ActorRef[T] (sending to the guardian,
whose Props[T] are provided for ActorSystem construction)
* removed the Actor trait: everything in there has been made into
messages and signals
* new Behavior[T] abstraction that consumes messages (of type T) or
Signals (lifecycle hooks, Terminated, ReceiveTimeout, Failed),
producing the next Behavior[T] as the result each time
* the ask pattern is provided and yields properly typed Futures
* variants of ActorContext are provided for synchronous testing of
Behaviors
All of this is implemented without touching code outside akka-typed
(apart from making guardianProps configurable), creating wrapper objects
around ActorRef, ActorContext, ActorSystem, Props and providing an Actor
implementation that just runs a Behavior.
* remove channels
* remove View
* remove Processor
* collapse the complicated internal state management
that was spread out between Processor, Eventsourced and Recovery
* remove Recovery trait, this caused some duplication between Eventsourced
and PersistentView, but but the enhanced PersistentView will not be based
on recovery infrastructure, and therefore PersistentView code will be replaced anyway
* remove PersistentBatch
* remove LoopMessage
* remove deleteMessages of individual messages
* remove Persistent, PersistentRepr and PersistentImpl are kept
* remove processorId
* update doc sample code
* note in migration guide about persistenceId
* rename Resequencable to PersistentEnvelope
