Set the server state to initialized so that dynamic configuration requests will be sent to the client. Rename the mutex that guards state. The state field was previously named initialized, so it only makes sense to similarly rename the mutex that guards the state field. Always unlock stateMu before calling other functions so that callees that need to check state can acquire the lock.
