Manuel Ung 8ad63a4b86 WriteUnPrepared: Add new WAL marker kTypeBeginUnprepareXID (#4069) ... Summary: This adds a new WAL marker of type kTypeBeginUnprepareXID. Also, DBImpl now contains a field called batch_per_txn (meaning one WriteBatch per transaction, or possibly multiple WriteBatches). This would also indicate that this DB is using WriteUnprepared policy. Recovery code would be able to make use of this extra field on DBImpl in a separate diff. For now, it is just used to determine whether the WAL is compatible or not.
