changelog: turn {de,en}code_extra methods into functions
The methods were not really methods -- they didn't use 'self'. Having
them as functions in the module it useful for other modules (like the
commitsigs extension) that want to recompute the changeset hash and
thus want to encode dicts the same way as changelog does it.
Removed the underbars from their names at the same time.
