Manuel Ung b9846370e9 WriteUnPrepared: Add support for recovering WriteUnprepared transactions (#4078) ... Summary: This adds support for recovering WriteUnprepared transactions through the following changes: - The information in `RecoveredTransaction` is extended so that it can reference multiple batches. - `MarkBeginPrepare` is extended with a bool indicating whether it is an unprepared begin, and this is passed down to `InsertRecoveredTransaction` to indicate whether the current transaction is prepared or not. - `WriteUnpreparedTxnDB::Initialize` is overridden so that it will rollback unprepared transactions from the recovered transactions. This can be done without updating the prepare heap/commit map, because this is before the DB has finished initializing, and after writing the rollback batch, those data structures should not contain information about the rolled back transaction anyway. Commit/Rollback of live transactions is still unimplemented and will come later.
