Rename std.string.toStringz?

It *is* a word. A stringz is a string that ends in zero. This
family of traditional names (STRINGZ, ASCIZ, etc.) predates C itself.

On the other hand, there is *no such thing* as a StringZ. You'd
never call it a "string zero". You'd call it a "zero terminated
string", or maybe a "C string".

Changing it to "toCString" is completely pointless, a cost without
a benefit, but at least it's not a completely nonsensical name like
toStringZ.
