WebServiceWorkerProxy instances can be unwrapped to ServiceWorkers.

WebServiceWorkerProxy instances can be unwrapped to ServiceWorkers.

This does not change behavior because Chrome's service worker
dispatcher always mints new WebServiceWorker instances, and
WebServiceWorker::proxy returns null.

PTAL

This is a bit crazy but the problem is constrained:

WebServiceWorkerProxy can't be a simple type that forwards calls to the
ServiceWorker (like WebNode does) because then Source/platform would depend on
modules for the implementation of the forwarding methods.

WebServiceWorkerProxy can't remain pure virtual because "unwrap" needs to
mention the specific WebCore::ServiceWorker type, which doesn't make sense in
public/platform.

Cribbing from WebArrayBuffer, perhaps even the INSIDE_BLINK stuff needs exports?

[dominicc (has gone to gerrit), 2014-06-01 08:28:46]

I'm going to assume that the tweaked exports and member visibility are OK and CQ
this, but if that is not right don't hesitate to roll it out and we can revisit
this.
