* Add a reference update to transaction. new_sha1 is the value that
* the reference should have after the update, or zeros if it should

+ * already exist and a new ref will be created with new_sha1.
* Function returns 0 on success and non-zero on failure. A failure to update
* means that the transaction as a whole has failed and will need to be
* rolled back.
