D7236: repoview: wrap changelog class when filtering

REVISION SUMMARY
  The class doesn't yet do anything. I'll move the filter-aware
  overrides from the changelog class over one by one to this class in
  coming patches. That will leave the changelog class simpler and will
  centralize more of the filtering logic to repoview. I could not
  measure any performance difference.
