Arne Schwabe 91fd9614f9 Change type of option flag from unsigned int to uint64_t
We currently use all 32 bits of the unsigned int for option classes.
While we can probably can retire 2-3 of the existing options, at some
point we will hit the limit again.

Instead of fully rewriting this logic to use a different approach or
structure, changing the type from unsigned int to uint64_t seem to be
a lot less intrusive approach.
