commit ae65b291893488bc1ca4fc9e6abc6bff160d4382

NetworkService: Add basic support for extension service workers.

Extensions can register service workers from URLs like
chrome-extension://blahblahblah/sw.js. To load such URLs we must
use ExtensionURLLoaderFactory instead of the NetworkService.

This patch allows extension service workers to be registered.
But it doesn't yet allow subresource requests to fallback to
the ExtensionURLLoaderFactory.

This enables 41 of 49 failing browser tests.

S13nServiceWorker: Save the ptr to non_network_loader_factory.

ServiceWorkerNewScriptLoader was using the ptr then letting it fall
out of scope. ServiceWorkerScriptLoaderFactory still held a ptr to the
factory which is strongly bound, so the factory shouldn't die anyway,
but it seems safer if ServiceWorkerNewScriptLoader holds the cloned
ptr too throughout its life.

I'm not sure if this is actually needed for ExtensionURLLoaderFactory,
but it seems possible to write a factory that would fail if the
cloned ptr falls out of scope.

NetworkService: Support subresource requests to extension service workers.

This CL makes it so ServiceWorkerSubresourceLoaderFactory uses a
factory created from a ChildURLLoaderFactoryBundle rather than the direct
network factory for "network fallback" after service worker does
not provide a response to a FetchEvent.

The direct network factory didn't work in the case of
chrome-extension:// URLs, since network service does not understand
such URLs.

To create the fallback factory, we use the default
ChildURLLoaderFactoryBundle of the RenderFrameImpl, except remove the
"default factory" from that bundle. The default factory can be something
like the AppCache loader factory, which we don't want to hit when
performing network fallback.

Closing this as the browser tests now pass. The remaining failing test ServiceWorkerTest.MimeHandlerView has to do with NetworkService + mimeHandler which seems independent of service workers. jam@ said he will take that.

service worker: Use URLLoaderFactoryBundle for loading new scripts.

Before this CL, the service worker script loader factories had both
a network loader factory and non-network loader factory, and chose
which one to use based on the URL scheme. A URLLoaderFactoryBundle can
be used for that instead, which simplifies code as the factories
just need a single abstract SharedURLLoaderFactory.
