component AP gateway: AP <=> XMPP reactions conversions: - Pubsub Attachments plugin has been renamed to XEP-0470 following publication - XEP-0470 has been updated to follow 0.2 changes - AP reactions (as implemented in Pleroma) are converted to XEP-0470 - XEP-0470 events are converted to AP reactions (again, using "EmojiReact" from Pleroma) - AP activities related to attachments (like/reactions) are cached in Libervia because it's not possible to retrieve them from Pleroma instances once they have been emitted (doing an HTTP get on their ID returns a 404). For now those cache are not flushed, this should be improved in the future. - `sharedInbox` is used when available. Pleroma returns a 500 HTTP error when ``to`` or ``cc`` are used in a direct inbox. - reactions and like are not currently used for direct messages, because they can't be emitted from Pleroma in this case, thus there is no point in implementing them for the moment. rel 371
