Avoid out-of-bound array access in API tests The API tests combine string buffers with arbitrary length values which makes ASan detect out-of-bound array accesses. Even without ASan, this could lead to unwanted test failures. Add a check for "len", "size", and "start" arguments, assuming they apply to the nearest char pointer. Skip the test if they exceed the buffer size. This is a somewhat naive heuristic but it seems to work well.
