  TlsVersion/TlsVersionFromString, GetClientConnectURLs, ResolveHostPorts,
  PortsInfo/PortFile/LogPorts, ReadyForListeners, GetRandomIP, AcceptError
- Internal/WaitGroup.cs: Go-style WaitGroup using TaskCompletionSource

Modified:
- Auth/AuthTypes.cs: Account now implements INatsAccount (stub)
- NatsServerTypes.cs: ServerInfo.ShallowClone(), removed duplicate RefCountedUrlSet
- NatsServer.cs: _info promoted to internal for test access
- Properties/AssemblyInfo.cs: InternalsVisibleTo(DynamicProxyGenAssembly2)
- ServerTests.cs: 20 new session-10 unit tests (GenerateInfoJson, TlsVersion,
