Improve error handling with separate ICanErrorListener

Error handling highlights:
- moved onError from ICanMessageListener to ICanErrorListener
- added isFatal callback argument to request client disconnect
- don't down interface that's already down

Also:
- don't crash if it's not possible to unregister ICanBus
- don't crash while trying to down interface that failed
- make hidl-utils available to vendor libraries
