Please remove this.

nullptr.

> Source/WebCore/page/UserContentController.h:74
> +    void addUserMessageHandlerDescriptor(UserMessageHandlerDescriptor*);
> +    void removeUserMessageHandlerDescriptor(UserMessageHandlerDescriptor*);

These should be references.

> Source/WebCore/page/UserMessageHandler.cpp:49
> +    m_descriptor->client().didPostMessage(*this, value.get());

You can just pass prpValue.get() directly here and get rid of the RefPtr variable. (And rename prpValue to value).

> Source/WebCore/page/UserMessageHandler.h:39
> +    static PassRef<UserMessageHandler> create(Frame* frame, UserMessageHandlerDescriptor& descriptor)

Frame&.

> Source/WebCore/page/UserMessageHandler.h:51
> +    explicit UserMessageHandler(Frame*, UserMessageHandlerDescriptor&);

This doesn't have to be explicit.

> Source/WebCore/page/UserMessageHandlersNamespace.h:47
> +    static PassRef<UserMessageHandlersNamespace> create(Frame* frame)

Frame&.

> Source/WebCore/page/UserMessageHandlersNamespace.h:57
> +    explicit UserMessageHandlersNamespace(Frame*);

Frame&.

> Source/WebCore/page/WebKitNamespace.h:43
> +    static PassRefPtr<WebKitNamespace> create(Frame* frame)

Frame&.

> Source/WebCore/page/WebKitNamespace.h:53
> +    explicit WebKitNamespace(Frame*);

Frame&.

> Source/WebKit2/UIProcess/API/Cocoa/WKScriptMessage.mm:46
> +    _body = body;

I think you want to copy the body as well.

> Source/WebKit2/UIProcess/API/Cocoa/WKUserContentController.mm:127
> +        [NSException raise:NSInvalidArgumentException format:@"Attempt to add ScriptMessageHandler with name '%@' when one already exists.", name];

No need to capitalize ScriptMessageHandler, can just be "script message handler".

> Source/WebKit2/UIProcess/UserContent/WebUserContentControllerProxy.cpp:133
> +        WebProcessProxy* webProcess = WebProcessProxy::fromConnection(connection);

Wonky indentation.

These have the wrong path.

This is not how we indent things in WebKit!.

It will break the !ENABLE(USER_MESSAGE_HANDLERS) build, because
this class is inside this guard, we can't use it outside.

I didn't want to remove the r+ intentionally, but my comment conflicted with the r+.

This doesn't handle every object. At the very least we should handle arrays.

Mac rebaselines landed in https://trac.webkit.org/changeset/169044 to try to
unbreak red buildbots and dead EWS bots. Could you possibly verify if the
new results are correct or not? (if you don't have time to wait for EWS ...)
