Problem:
========
- After commit cc8eefb0dc (MDEV-33087),
InnoDB does use bulk insert operation for ALTER TABLE.. ALGORITHM=COPY
and CREATE TABLE..SELECT as well. InnoDB fails to clear the bulk
buffer when it encounters error during CREATE..SELECT. Problem
is that while transaction cleanup, InnoDB fails to identify
the bulk insert for DDL operation.
Fix:
====
- Represent bulk_insert in trx by 2 bits. By doing that, InnoDB
can distinguish between TRX_DML_BULK, TRX_DDL_BULK. During DDL,
set bulk insert value for transaction to TRX_DDL_BULK.
- Introduce a parameter HA_EXTRA_ABORT_ALTER_COPY which rollbacks
only TRX_DDL_BULK transaction.
- bulk_insert_apply() happens for TRX_DDL_BULK transaction happens
only during HA_EXTRA_END_ALTER_COPY extra() call.
