Michael Jones 26f1770e53 [libc] clean up ctype negative handling ...

The ctype functions will sometimes be passed negative numbers, such as
EOF. Some of the previous implementations didn't handle these properly.
Additionally, the tests did not check any negative numbers. These
problems have been fixed.
