Currently replies to messages are handled in status-react.
This causes some issues with the fact that sometimes replies might come
out of order, they might be offloaded to the database etc.
This commit changes the behavior so that status-go always returns the
replies, and in case a reply comes out of order (first the reply, later
the message being replied to), it will include in the messages the
updated message.
It also adds some fields (RTL,Replace,LineCount) to the database which
were not previously saved, resulting in some potential bugs.
The method that we use to pull replies is currently a bit naive, we just
pull all the message again from the database, but has the advantage of
being simple. It will go through performance testing to make sure
performnace are acceptable, if so I think it's reasonable to avoid some
complexity.
This commit does a few things:
1) Handle membership updates using protobuf and adds the relevant
endpoints.
2) Store in memory a map of chats + contacts for faster lookups, which
are then flushed to disk on each update
3) Validate incoming messages
Sorry for the large pr, but you know, v1 :)
* Use a single Message type `v1/message.go` and `message.go` are the same now, and they embed `protobuf.ChatMessage`
* Use `SendChatMessage` for sending chat messages, this is basically the old `Send` but a bit more flexible so we can send different message types (stickers,commands), and not just text.
* Remove dedup from services/shhext. Because now we process in status-protocol, dedup makes less sense, as those messages are going to be processed anyway, so removing for now, we can re-evaluate if bringing it to status-go or not.
* Change the various retrieveX method to a single one:
`RetrieveAll` will be processing those messages that it can process (Currently only `Message`), and return the rest in `RawMessages` (still transit). The format for the response is:
`Chats`: -> The chats updated by receiving the message
`Messages`: -> The messages retrieved (already matched to a chat)
`Contacts`: -> The contacts updated by the messages
`RawMessages` -> Anything else that can't be parsed, eventually as we move everything to status-protocol-go this will go away.
