backport fix for mysql bug#12161 (XA and binlog)

Details

    Description

      5.7 finally fixes the 10-yr-old bug#12161 — a.k.a. prepared XA transactions are lost on disconnect. They solved it by introducing a new XA_prepare_log_event. As we'll need to be able to read this event, we can as well merge the whole fix for this bug.

            The latest patch needed more work. I am waiting for a next one.

            The issue duplicates an earlier reported MDEV-742. This one is closed in favor to proceed with the work in the latter one.
