Module strings

Helpers to write CStrings

The std::ffi::CString type does not implement std::io::Write (since it cannot support values containing zero bytes), so we implement our own wrappers.

One way is to use WriteIntoCString::write_into, which takes a closure, which then takes a writer.

Another is to create a CStringWriter explicitly.
