I think this is getting pretty close. Could you implement `asprintf` as well? It will simply call into the same interface as `vasprintf` most likely, see `vsprintf` and `sprintf` for example. I would also like some tests that require more `realloc` calls, something like `vasprintf("%200s%200s%200s", "a", "b", "c")` or similar. Also the tests should be using `LIBC_NAMESPACE::free`.
