------- Additional Comments from Renata Hodovan <reni at webkit.org>
> Why is this custom error() impl needed? CachedResource::error only contains
an additional m_data.clear() - that can't hurt, so why not leave it to the
base-class?
Right, I removed it.

Changelog is also updated. This first part contains just a minimal explanation
about the newly added classes. The functionality and its description will be in
the follow-up patch.
