The signature of the `Raw` methods has been changed so that they return
the application messageID.
Clients will keep track of this ID and receive a notification through
the envelopesMonitor of the state of the envelopes (sent/expired).
Envelopes monitor is passed this ID as well.
We use an array of IDs as datasync messages might be batched.
This commits adds two API calls:
SaveChat
GetChats
The first one behaves like an upsert.
The second takes two parameters, from, to and returns chats in reverse
order by timestamp.
Members and MembershipUpdates have been stored as blob of data to
simplify the querying (we never query them separately).
This commit adds the ability of reading and sending datasync messages.
Datasync messages are batched, so a single whisper message might
contain multiple protocol messages.
Datasync messages are parsed regardless of whether the datasync flag is
on, as this commit is backward compatible.
Sending messages is toggled off by default.
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`.
