+ Add reply blocks to _WKRemoteObjectInterface similar to NSXPCConnection
+ https://bugs.webkit.org/show_bug.cgi?id=151056
+ rdar://problem/23222609
+
+ Reviewed by Tim Horton.
+
+ * Platform/spi/Cocoa/NSInvocationSPI.h:
+ Add NSBlockInvocation declaration.
+
+ * Shared/API/Cocoa/RemoteObjectInvocation.mm:
+ (WebKit::RemoteObjectInvocation::encode):
+ Encode true if we have a reply ID.
+
+ * Shared/API/Cocoa/RemoteObjectRegistry.h:
+ Add new members.
+
+ * Shared/API/Cocoa/RemoteObjectRegistry.messages.in:
+ Add new CallReplyBlock message.
+
+ * Shared/API/Cocoa/RemoteObjectRegistry.mm:
+ (WebKit::RemoteObjectRegistry::sendReplyBlock):
+ Just send the CallReplyBlock message.
+
+ (WebKit::RemoteObjectRegistry::callReplyBlock):
+ Call through to _WKRemoteObjectRegistry.
+
+ * Shared/API/Cocoa/WKRemoteObjectCoder.h:
+ Pass an optional reply selector.
+
+ * Shared/API/Cocoa/WKRemoteObjectCoder.mm:
+ (encodeInvocationArguments):
+ Don't hard-code the first argument index.
+
+ (encodeInvocation):
+ Encode block invocations.
+
+ (-[WKRemoteObjectDecoder initWithInterface:rootObjectDictionary:replyToSelector:]):
+ Initialize _replyToSelector.
+
+ (validateClass):
+ NSBlockInvocation doesn't need to conform to NSSecureCoding.
+
+ (decodeInvocationArguments):
+ Don't hard-code the first argument, take it as a parameter instead.
+
+ (decodeInvocation):
+ Decode NSBlockInvocations (reply block invocations).
+
+ (decodeObject):
+ Check for NSBlockInvocation.
+
+ * Shared/API/Cocoa/_WKRemoteObjectInterface.mm:
+ (-[_WKRemoteObjectInterface _methodSignatureForSelector:]):
+ Return null if we can't find the method.
+
+ (-[_WKRemoteObjectInterface _methodSignatureForReplyBlockOfSelector:]):
+ Look up the reply block signature and return it.
+
+ (-[_WKRemoteObjectInterface _allowedArgumentClassesForReplyBlockOfSelector:]):
+ Look up the allowed reply argument classes and return them.
+
+ * Shared/API/Cocoa/_WKRemoteObjectInterfaceInternal.h:
+ Add new methods.
+
+ * Shared/API/Cocoa/_WKRemoteObjectRegistry.mm:
+ (PendingReply::PendingReply):
+ Add new object that represents a pending reply.
+
+ (-[_WKRemoteObjectRegistry _sendInvocation:interface:]):
+ If the invocation has a reply block, add a pending reply to our map.
+
+ (-[_WKRemoteObjectRegistry _invokeMethod:]):
+ If the method we're about to invoke has a reply block, construct a special reply block that calls us back with an invocation.
+ Encode this invocation and send it back across the wire.
+
+ (-[_WKRemoteObjectRegistry _callReplyWithID:blockInvocation:]):
+ Find the pending reply, decode the reply block invocation and call it.
+
+ * Shared/API/Cocoa/_WKRemoteObjectRegistryInternal.h:
+ Add new methods.
