Deprecate ChangeLog on bleeding_edge.

- This adds a sentinel to the ChangeLog on bleeding edge.
- Modifying the ChangeLog file directly when pushing to trunk is now no longer possible. If further modifications to the ChangeLog in manual push-to-trunk mode are required (e.g. after the prepare push LGTM), the change log entry temp file must be edited.
- Functionality that is no longer needed is removed.
