Now we can use EnumTraits<blink::mojom::ServiceWorkerEventStatus>. We already
have TypeConvertor to ServiceWorkerStatusCode at [1], so I think we can have
similar code.

Example of typemapping using EnumTraits:

Is it possible to convert 'const Callback<void
(::blink::mojom::ServiceWorkerEventStatus, base::Time)>' to 'const Callback<void
(content::ServiceWorkerStatusCode, base::Time)>' using EnumTraits?

[horo, 2016/09/23 09:13:35]

Ah, I misunderstood about typemap and EnumTraits.
I succeeded to use EnumTraits in Pathc Set 4.
