"C strings" ought to be anathema in Parrot. When someone talks about a
"C string" you should look at them as if they have just said a dirty word.

Going from a STRING to "C string" means throwing away encoding and
charset information, which means you are left with a string of bytes
that mean ABSOLUTELY NOTHING. I think if we do implement such a function
it should return the string transcoded into Double-Byte Character Set
EBCDIC, just to make the point.

No C strings, please.
