repoview: wrap changelog class when filtering
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.
