Chat Federation: refactoring ActivityPub data:
The data format used by plugin v6.3.0 was not well suited.
Here comes a new data format, with S2S informations.
The plugin can automatically upgrade old format.
It also continues to provide the old format, so than remote instance
that did not update the plugin will still work.
