 *
 * - `out` is a pointer that receives the resulting repository object
 * - `origin_remote` is a remote which will act as the initial fetch source
 * - `workdir_path` is local directory to clone to
 * - `fetch_progress_cb` is optional callback for fetch progress. Be aware that
 *   this is called inline with network and indexing operations, so performance
 *   may be affected.
 * - `fetch_progress_payload` is payload for fetch_progress_cb
 * - `checkout_opts` is options for the checkout step. If NULL, no checkout
 *   is performed
