Move 'response' check in responseReceived() to the backend.

Removed the response parameter check in responseRequest() and moved
it to the backend. This resolves a FIXME.
Also removed the existance check in _updateNetworkRequestWithResponse
because only the responseRequest() calls it.

This CL adds support for tracing through OwnPtr's and adds a trace method to all supplements. Notice that trace is only called on supplements that are properly traced via the Supplementable classes.
