Fix long standing bug that prevented newer drivers from working with
older libGL. The data in extension_helper.h erroneous instructed
drivers to expect all functions with establised offsets, even those
not in the ABI, to have a specific offset allocated. This is just
wrong. A function is either in the ABI and has a set offset or a
function is not in the ABI and has a re-map offset.
