AppCache INTERCEPT namespace.

- Add support for a custom CHROMIUM CACHE MANIFEST signature. Other browsers should ignore files with this signature.
- Parse intercept namespace entries out of the new CHROMIUM-INTERCEPT manifest section. Other browsers should ignore this entire section.
- Store and retrieve the new kind of namespace records in the database layer.
- Upgrade existing databases to the new schema.
- Look for matches in the new namespaces when handling main and sub resource requests.
- Add unit tests.
