I dislike the static hash table to cache the integer counter for numbered paths. Let's instead cache the counter at the class instance itself -- since the class contains the information how the export path should be exported. However, we cannot use a plain integer field inside the class structure, because the class is copied between derived classes. For example, NMDeviceEthernet and NMDeviceBridge both get a copy of the NMDeviceClass instance. Hence, the class doesn't contain the counter directly, but a pointer to one counter that can be shared between sibling classes.
