PlzWorker: Initiate top-level worker script loading for Shared Workers from the browser process
This CL adds SharedWorkerScriptFetcher that initiates a top-level worker script
loading for shared workers from the browser process. Once the fetcher receives a
response head, that unbounds the URL loader and its client, and passes them to
the renderer process with the StartWorker message. In the renderer process,
WorkerClassicScriptLoader in Blink makes a resource request as usual, and
ResourceDispatcher in Content serves it using the passed URLLoader etc.
In addition, this CL makes Shared Workers run with AppCache on NetworkService,
AppCache's fallback case is not implemented yet though. Subsequent CLs will
implement the case.
See the design doc for more details:
