/*
 * Reference iterators
 *
 * A reference iterator encapsulates the state of an in-progress
 * iteration over references. Create an instance of `struct
 * ref_iterator` via one of the functions in this module.
 *
 * A freshly-created ref_iterator doesn't yet point at a reference. To
 * advance the iterator, call ref_iterator_advance(). If successful,
 * this sets the iterator's refname, oid, and flags fields to describe
 * the next reference and returns ITER_OK. The data pointed at by
 * refname and oid belong to the iterator; if you want to retain them
 * after calling ref_iterator_advance() again or calling
 * ref_iterator_abort(), you must make a copy. When the iteration has
 * been exhausted, ref_iterator_advance() releases any resources
 * associated with the iteration, frees the ref_iterator object, and
 * returns ITER_DONE. If you want to abort the iteration early, call
 * ref_iterator_abort(), which also frees the ref_iterator object and
 * any associated resources. If there was an internal error advancing
 * to the next entry, ref_iterator_advance() aborts the iteration,
 * frees the ref_iterator, and returns ITER_ERROR.
 *
 * The reference currently being looked at can be peeled by calling
 * ref_iterator_peel(). This function is often faster than peel_ref(),
 * so it should be preferred when iterating over references.
 *
 * Putting it all together, a typical iteration looks like this:
 *
 *     int ok;
 *     struct ref_iterator *iter = ...;
 *
 *     while ((ok = ref_iterator_advance(iter)) == ITER_OK) {
 *             if (want_to_stop_iteration()) {
 *                     ok = ref_iterator_abort(iter);
 *                     break;
 *             }
 *
 *             // Access information about the current reference:
 *             if (!(iter->flags & REF_ISSYMREF))
 *                     printf("%s is %s\n", iter->refname, oid_to_hex(iter->oid));
 *
 *             // If you need to peel the reference:
 *             ref_iterator_peel(iter, &oid);

/*
 * Read a reference from the specified reference store, non-recursively.
 * Set type to describe the reference, and:
 *
 * - If refname is the name of a normal reference, fill in oid
 *   (leaving referent unchanged).
 *
 * - If refname is the name of a symbolic reference, write the full
 *   name of the reference to which it refers (e.g.
 *   "refs/heads/master") to referent and set the REF_ISSYMREF bit in
 *   type (leaving oid unchanged). The caller is responsible for
 *   validating that referent is a valid reference name.
 *
 * WARNING: refname might be used as part of a filename, so it is
 * important from a security standpoint that it be safe in the sense
 * of refname_is_safe(). Moreover, for symrefs this function sets
 * referent to whatever the repository says, which might not be a
 * properly-formatted or even safe reference name. NEITHER INPUT NOR
 * OUTPUT REFERENCE NAMES ARE VALIDATED WITHIN THIS FUNCTION.
 *
 * Return 0 on success. If the ref doesn't exist, set errno to ENOENT
 * and return -1. If the ref exists but is neither a symbolic ref nor
 * an object ID, it is broken; set REF_ISBROKEN in type, set errno to
 * EINVAL, and return -1. If there is another error reading the ref,
 * set errno appropriately and return -1.
 *
 * Backend-specific flags might be set in type as well, regardless of
 * outcome.
 *
 * It is OK for refname to point into referent. If so:
 *
 * - if the function succeeds with REF_ISSYMREF, referent will be
 *   overwritten and the memory formerly pointed to by it might be
 *   changed or even freed.
 *
 * - in all other cases, referent will be untouched, and therefore
 *   refname will still be valid and unchanged.
