* Remove noise padding payload (spec removed it) * add log scope in secure * avoid defect array out of range in switch secure when "na" * improve identify traces * wip noise fixes * noise protobuf adjustments (trying) * add more debugging messages/traces, improve their actual contents * re-enable ID check in noise * bump go daemon tag version * bump go daemon tag version * enable noise in daemonapi * interop testing, (both secio and noise will be tested) * azure cache bump (p2pd) * CI changes - Travis: use Go 1.14 - azure-pipelines.yml: big cleanup - Azure: bump cache keys - build 64-bit p2pd on 32-bit Windows - install both Mingw-w64 architectures * noise logging fixes * alternate testing between noise and secio * increase timeout to avoid VM errors in CI (multistream tests) * refactor heartbeat management in gossipsub * remove locking within heartbeat * refactor heartbeat management in gossipsub * remove locking within heartbeat Co-authored-by: Ștefan Talpalaru <stefantalpalaru@yahoo.com>
