ctype.h: wrapper ctype functions with a cast to (unsigned char)

ctype functions take an *int*, which the user is expected to have
taken the input character from getc() and friends, or taken a
character and cast it to (unsigned char).

We don't care about EOF (-1), so use macros that cast to (unsigned
char) for us.
