Log Message:
lint: add wrapper for <ctype.h> functions, for strict bool mode

When using the Clang preprocessor (with MKLLVM=yes), the preprocessor
output does not indicate which tokens come from a system header and
which tokens come from the user code.  Lint's strict bool mode relies on
this information to treat the character classification functions from
<ctype.h> as if their return type were bool instead of int.

These wrapper functions are only used when their argument is indeed a
'char', but not when the argument might be 'EOF or representable as an
unsigned char', such as when reading a byte from the input.
