Make LayoutTests/http/tests/misc/redirect-to-external-url.html PASS.

 * Implement WebFrameLoaderClient::dispatchUnableToImplementPolicy()
 * Implement WebFrameLoaderClient::canHandleRequest() so that an
   unkown scheme makes ResourceError.
   - Introduce WebFrameClient::canHandleRequest() to avoid chrome::
     dependency from webkit/glue.
   - Introduce WebFrameClient::cannotShowURLError() to keep
     transparency of WebURLError.
 * Introduce WebFrameClient::unableToImplementPolicyWithError()
   An implmentation in test_shell prints the message same as WebKit.
