This is the idea, no commitment to use outside tools/ living code at
this point.

Anybody can try and provide comments on his mileage, but we're still at
a too early stage for any kind of commitments.

But yeah, everybody, I think, agrees that the ball needs to keep on
rolling on the direction of avoiding code duplication for tools/ living
code.

Back to Namhyung's suggestion, yeah, tools/lib/kapi/ would consume just
one more letter and would further disambiguate things.

But this can be done later if Borislav is unconvinced at this point.
