Multiple fixes:

- Probably fix "more-geturl-bugs", but hard to verify.
  - Fix "last-modified-problem", approximately.  (Difficult or impossible
    in the general case for externally-retrieved content.)
  - Fix "rss-syndication".
  - Fix unnamed bug where Database caches would try to Storable::freeze
    non-references and thereby crash.
  - Fix "apache-version-component-in-wrong-place".
