introduce GSM_MCC_MNC_INVALID
In some cases, we want to mark an unset MCC-MNC. Define uint16-max for this purpose. osmo-bsc code is already doing so with a -1 and using int data types, which will become inconvenient with the new API that handles MCC and MNC as uint16_t. Change-Id: Ieee7add0bd6d94cf84743a49794bbcd38561b72f
