Use counter in client to server messages to avoid duplicate handling (#11733)
An server message id counter is included in every client to server message and an
expected id is included in every server to client message. This makes it safe to
re-send any message when the client is not 100% sure the server has received the
message, without having to worry about double handling on the server side.
