Stop implicitly casting the child prefix/index to int. It can have high bits set thus get promoted to wildly incorrect value and cause chaos further on. In addition, convert the existing `unsigned char` instances to uint8_t, which better illustrates what we're after - a fixed sized 8 bit unsigned integer.

As a follow-up to #247 it addresses all the
s/int/unsigned char/instances that I could find.It also forces
chartounsigned char, since that's the majority(?) of our use case.NOTE: the PR is completely untested, hence marked as draft
Once the linked PR has landed and we have agreement if
-funsigned-charis something we'd really want, I will grab a few old and new kernels and do some testing.
