So basically av_ctz was a bungled operation. Someone needed it for
flacdec, and decided to add it to intmath with the av_ prefix. We
should get rid of this while we still have the window available. As
obviously I do not know what is API/ABI clearly enough, I will refrain
from sending a patch and leave it in more capable hands.
