This patch looks like it's in pretty good shape.  I've left you a couple minor comments below.  Once those are addressed, we should be all set.  Thanks!

Typically new files are licensed using BSD, but it's up to you.

> Source/WebCore/page/CustomHandlersState.cpp:27
> +String customHandlersStateString(CustomHandlersState state)

Rather than creating a whole new file for this rather simple function, you can declare the CustomHandlersState enum in ChromeClient.h and have the client method return an enum value rather than a string.  Then you can do the translation between enum values and strings in a static function in NavigatorRegisterProtocolHandler.cpp.

document can never be 0 here.

> Source/WebCore/page/NavigatorRegisterProtocolHandler.cpp:182
> +    if (!document)
> +        return;

ditto

> Source/WebCore/page/NavigatorRegisterProtocolHandler.idl:27
> +#if defined(ENABLE_REGISTER_PROTOCOL_HANDLER) && ENABLE_REGISTER_PROTOCOL_HANDLER

You can just use the [Conditional] attribute on the method.
