This adds gossipsub and floodsub, as well as basic interop testing with the go libp2p daemon. * add close event * wip: gossipsub * splitting rpc message * making message handling more consistent * initial gossipsub implementation * feat: nim 1.0 cleanup * wip: gossipsub protobuf * adding encoding/decoding of gossipsub messages * add disconnect handler * add proper gossipsub msg handling * misc: cleanup for nim 1.0 * splitting floodsub and gossipsub tests * feat: add mesh rebalansing * test pubsub * add mesh rebalansing tests * testing mesh maintenance * finishing mcache implementatin * wip: commenting out broken tests * wip: don't run heartbeat for now * switchout debug for trace logging * testing gossip peer selection algorithm * test stream piping * more work around message amplification * get the peerid from message * use timed cache as backing store * allow setting timeout in constructor * several changes to improve performance * more through testing of msg amplification * prevent gc issues * allow piping to self and prevent deadlocks * improove floodsub * allow running hook on cache eviction * prevent race conditions * prevent race conditions and improove tests * use hashes as cache keys * removing useless file * don't create a new seq * re-enable pubsub tests * fix imports * reduce number of runs to speed up tests * break out control message processing * normalize sleeps between steps * implement proper transport filtering * initial interop testing * clean up floodsub publish logic * allow dialing without a protocol * adding multiple reads/writes * use protobuf varint in mplex * don't loose conn's peerInfo * initial interop pubsub tests * don't duplicate connections/peers * bring back interop tests * wip: interop * re-enable interop and daemon tests * add multiple read write tests from handlers * don't cleanup channel prematurely * use correct channel to send/receive msgs * adjust tests with latest changes * include interop tests * remove temp logging output * fix ci * use correct public key serialization * additional tests for pubsub interop
