Darin had a good suggestion for how to establish the frame/datasource/appcache
relationships. Instead of adding a WebFrame param to the factory method, move
the createApplicationCacheHost() method from WebKitClient to WebFrameClient.
That interface has a handful of similar factory methods that take a WebFrame
param.

So we'd have...

WebFrameClient::createApplicationCacheHost(
  WebFrame*, WebDataSource*, WebApplicationCacheHostClient*);

... at the time of WebApplicationCacheHost construction (its done lazily in
maybeLoadMainResource), we're guaranteed to know what our WebCore::Frame is.


And we wouldn't need the WebDataSource.frame() method which Darin wants to
avoid introducing.
