Reports whether the system has changes that require a refresh.
Sensors can undergo autonomous state changes that require client state to be refreshed (e.g. sensor goes offline). The GoSystem_HasChanges function can be used to determine if such changes have occurred.
The GoSystem_HasChanges function does not perform communication, and consequently, will not require the caller to block for a long duration. If changes are detected, the GoSystem_Refresh function can be called to resolve the changes.
This method is thread-safe.
