I'd use `unsigned char`.  I *might* consider `typedef unsigned
char byte;`, but I probably wouldn't bother.  I know exactly what
`unsigned char` means, and I'd expect the same of anyone reading
my code.  I don't consider it unwieldy -- though I might have preferred
it if the language had made "byte" a keyword.

Yes.

As for "u8", I see no point in inventing new naming conventions for
existing entities that already have perfectly good names.  (Saving a few
keystrokes is a negligible advantage, far outweighed by the added
confusion.)
