changeset 45573:9a3563b46f52

changelog: add a `changes` property on `changelogrevision` For the sidedata storage we are moving toward "all in one" block containing the equivalent of a "ChangingFiles" instance. We do various refactoring beforehand to prepare the usage of theses new data in the code. Since the object use slots, the "property cache" tricks cannot be used, and we cache the value manually.
