[PATCH v11 01/41] refs.c: remove ref_transaction_rollback

Message-ID: <1401222360-21175-2-git-send-email-sahlberg@google.com>
In-Reply-To: <1401222360-21175-1-git-send-email-sahlberg@google.com>

We do not yet need both a rollback and a free function for transactions. Remove ref_transaction_rollback and use ref_transaction_free instead.

At a later stage we may reintroduce a rollback function if we want to start adding reusable transactions and similar.
