Errors when generating a DH secret where silently ignored, resulting in
invalid key material being used.
This commit fixes the issue by upgrading the double ratchet library
and implementing the updated interface, which uses now slices instead of fixed bytes keys.
This commit does a few things:
1) Add replies to messages, which are calculated at query time using a
join
2) Add a BlockContact api call that takes care of deleting messages from
a user, deleting the chat, and re-compute the denormalized values. As it
needs to run in a transaction, the method that it relies on take a
transaction as an optional parameter.
3) Change ID scheme for chats/contacts so that it's consistent across
messages/contacts
This is not compatible as I have modified a migration, but it's not a
problem as data compatibility can be broken
status-go requires some special methods to be exposed in order to support the current integration.
Introduced families of methods marked as `DEPRECATED`:
* `SendRaw` to send transit-encoded messages, both public and private. It supports only private PFS-enabled messages. To send private non-PFS messages, we can add this functionality or it needs to happen through `shh_post` directly from status-react.
* `RetrieveRawAll` and `RetrieveRawWithFilter` to get retrieve decrypted but transit-encoded messages.
* `LoadFilters` and `RemoveFilters` to manage Whisper filters directly.
* By default, persistence of messages is disabled. It can be enabled with an option passed to `Messenger`.
* File paths to the databases are configurable in `Messenger`.
