This change flattens messaging/chat package. It also removes dependency between multidevice and chat/protobuf packages.
The Publisher interface was also changed a bit to support more native types.
Version got bumped to 0.29.0-beta.3.
* Move installations to status-go
This commit moves installations management/storage to status-go.
We remove the native binding and provide RPC endpoints to set the
metadata and return a list of our own installations.
* Cache keys
Generating a symkey can take up to a second on slow devices, this commit
makes so that keys are saved once generated and stored in the database.
This commit add topic negotiation to the protocol.
On receiving a message from a client with version >= 1, we will generate
a shared key using Diffie-Hellman. We will record also which
installationID has sent us a message.
This key will be passed back to the above layer, which will then use to
start listening to a whisper topic (the `chat` namespace has no
knowledge of whisper).
When sending a message to a set of InstallationIDs, we check whether we
have agreed on a topic with all of them, and if so, we will send on this
separate topic, otherwise we fallback on discovery.
This change is backward compatible, as long as there is no downgrade of
the app on the other side.
A few changes:
* Factored out the DB in a separate namespace as now it is
being used by multiple services (TopicService and EncryptionService).
* Factored out multidevice management in a separate namespace
* Moved all the test to test the whole protoocl rather than just the encryption service
* Moved all the filter management in status-go
