Plumb request interception into the appcache library for both chrome and test_shell.

AppCache library:
* Added AppCacheInterceptor, which is derived from URLRequest::Interceptor.

Chrome:
* Each UserProfile instantiates a ChromeAppCacheService, which is derived from an appcache library class.
* Each ChromeURLRequestContext associated with that profile has a reference to that instance.
* ResourceDispatcherHost pokes AppCacheInterceptor when initiating URLRequests and when returning the response head.

TestShell:
* Added SimpleAppCacheSystem which bundles together appcache lib components for use in a single process with an UI and IO thread.
* TestShellWebKit instantiates and initializes an instance of the above, aimed at at temp directory that will get cleaned up when the test run is over.
* SimpleResourceLoaderBridge pokes the system when initiating URLRequests and when returning the response head.

TEST=none, although many existing tests exercise this stuff
BUG=none
