C-toxcore: History sync via trusted node or another client

[MAH69IK]

I use Tox on 3 devices: home laptop, work computer and telephon. Will be great if Tox can sync chat history to all devices. For example - from trusted node (I have my own node). Or if I can sync history from my friend's Tox (I send messages from work to my friend, go home, run tox and load this messages to history from friend's client).

Yes, this is a good idea. I have some ideas on how to implement this (and many other features) in one go.

@MAH69IK @iphydf we would need MsgV2 first, to have uniqe IDs for all messages.
otherwise it will be difficult to sync messages

with that and a good sync logic we can implement multidevice for messages in an easy way.
