argv-array: add detach function
The usual pattern for an argv array is to initialize it, push in some strings, and then clear it when done. Very occasionally, though, we must do other exotic things with the memory, like freeing the list but keeping the strings. Let's provide a detach function so that callers can make use of our API to build up the array, and then take ownership of it.
