Instead of adding driver IDs by hand to a header file, generate the driver ID from the (hopefully unique) name of the driver. This means one file less for driver authors to modify, and one possible source of merge conflicts less as well. However, this means that already enrolled fingerprints will need to be enrolled again, as the driver IDs will have changed compared to their old on-disk value.
