Andrew Sutherland 6e5b348a26 Bug 1113522 - ExtendableMessageEvent.source should be ServiceWorker-aware. r=dom-worker-reviewers,edenchuang
ServiceWorkers aren't exposed as clients, so when we are sending a postMessage
from them, we need to capture their ServiceWorkerDescriptor and propagate that
instead of the client state.
