Merge the add/get providers messages with the discovery v5 messages inside of the discovery v5 code. Discovery v5 uses RLP encoding, while the add/get providers uses protobufs, as per the libp2p spec. The merge of these two uses RLP on the outer wrapper of the message, and a protobuf-encoded blob on the “inside” for the add/get providers messages only. Eventually this needs to change so that we use protobufs only.
There is still some code in the libp2pdht/dht directory, which is being read from the discovery v5 directory. Eventually these two should merge as well.
Project has been updated to use nimble as a build system. All required dependencies have been added.
All nim-eth mirrored files were added to a private folder in the libp2pdht module. A libp2pdht/discv5 module was added to alias the nim-eth modules (which will change over time).
Test have been updated to use status-im/asynctest. This PR uses a branch of asynctest that supports async suite before/after. This seemed like the only the tests would work without throwing gcsafe errors.
All tests working.
