Publish appropriate events to the current ActorSystem event stream upon remote ActorSystem shutdown or when current ActorSystem is quarantined by the remote ActorSystem.
* DeathPactException could occur if the ReliableDeliverySupervisor
was gated but not yet received Terminated and got an Ungate message
from the EndpointManager and thereby entered idle state, followed by
receiving the Terminated message, which is not handled in idle
* instead of using transport failure detector
* add a new config property akka.remote.handshake-timeout, but
for netty.tcp and netty.ssl the existing netty.tcp.connection-timeout
setting will be used
* add test of the timeouts
* mima filter for internal ProtocolStateActor
* well, as long as they provide the parseFrom and toByteArray
* it is using reflection to find the `parseFrom` and `toByteArray` methods to avoid
dependency to `com.google.protobuf`.
* also special case com.google.protobuf when loading serialization binding
* migration guide
* mima filters for the serializers (all types changed)
* add real test for ProtobufSerializer
- created new subproject akka-protobuf (and added COPYING and LICENSE)
- renamed com.google.protobuf -> akka.protobuf everywhere
- also added such renaming step to the results of protoc compilation in
project/Protobuf.scala
- had to include transcriptions of Netty’s ProtobufEncoder/Decoder to
make multi-node-testkit compile again
When watching many (5000) actors at the same time the
following problems were found:
* first send of a sys msg is sent without any flow control
=> limit the number of outstanding sys msg by using
the buffer to send them later (ordinary resend)
* when msg cannot be written sys msg is dropped (relying on resend),
but that cause message re-ordering and negative acknowledgment,
which is very costly
=> buffer the sys msg on write failure
=> minor optimization of AckedReceiveBuffer
I also made the resend-limit configurable.

* addunidoc task via an AutoPlugin that depends on PrValidation and Unidoc autoplugins
* separate cli option logic to a case class
* remove autoplugin for root project
* until we have replaced all internal usages of it,
or we could decide that it is good to keep as an
internal facility and then we can remove the deprecation
annotations
This improves the remote watching mechanism as follows: Watch requests
are intercepted by the RemoteWatcher and not sent on the wire,
excepted watches from the remoteWatcher itself.
RemoteWatcher is then in charge of forwarding DeathWatchNotification
messages to the watchers.
This reduces the number of watch message to one per watchee, even if
there are several watcher on the same watchee (instead of n+1 before).
Reversed watch messages, and watch on ref with undefinedUid are excluded from
interception by the RemoteWatcher and so are handled as before this commit.
In addition, the following changes are made:
- Keep watchers in a map watchee -> watchers for more efficient retrieval
(in a scala Multimap)
- Keep watchees in a map address -> watchee for more efficient retrieval
(in a scala Multimap)
- Use of InternalActorRef more thoroughly to avoid casts
- Rewatch use a standard watch message, as the distinction is longer needed
