BUG#29288: myisam transactions replicated to a transactional 

slave leaves slave unstable

Problem: when replicating from non-transactional to
transactional engine with autocommit off, no BEGIN/COMMIT
is written to the binlog. When the slave replicates, it
will start a transaction that never ends.

Fix: Force autocommit=on on slave by always replicating
autocommit=1 from the master.

# ==== Purpose ====
#
# Test replication of transactions on tables which have different
# engines on master and slave. This tests all combinations of innodb,
# myisam, and ndb.
#
# ==== Method ====
#
# Set up six tables, each being innodb, myisam, or innodb on master,
# and another of innodb, myisam, or innodb on slave. For each table,
# do the following:
#
# - committed and rollback'ed transactions, with autocommit on and
# off
# - non-transactions with autocommit on
# - non-transactions with autocommit off, where the master table is
# myisam.
#
# Note: we are running the slave with
# --replicate-ignore-table=mysql.ndb_apply_status . See BUG#34557 for
# explanation.
#
# ==== Related bugs ====
#
# BUG#26395: if crash during autocommit update to transactional table on master, slave fails
# BUG#29288: myisam transactions replicated to a transactional slave leaves slave unstable
# BUG#34557: Row-based replication from ndb to non-ndb gives error on slave
# BUG#34600: Rolled-back punch transactions not replicated correctly
#
# ==== Todo ====
#
# We should eventually try transactions touching two tables which are
# of different engines on the same server (so that we try, e.g. punch
# transactions; cf BUG#34600). However, that will make the test much
# bigger (9 master-slave engine combinations [myisam->myisam,
# myisam->ndb, etc]. To try all combinations of one or more such
# tables means 2^9-1=511 transactions. We need to multiplied by 5
# since we want to test committed/rollback'ed transactions
# with/without AUTOCOMMIT, as well as non-transactions with
# autocommit). We'd have to write a script to produce the test case.

If we don't use flags2 for anything else than options contained in
thd_arg->options, it would be more efficient to flags2=thd_arg->options
(OPTIONS_WRITTEN_TO_BIN_LOG would be used only at reading time).
But it's likely that we don't want to use 32 bits for 3 bits; in the future
we will probably want to reclaim the 29 bits. So we need the &.
We only replicate over the bits of flags2 that we need: the rest
are masked out by "& OPTIONS_WRITTEN_TO_BINLOG".
We also force AUTOCOMMIT=1. Rationale (cf. BUG#29288): After
fixing BUG#26395, we always write BEGIN and COMMIT around all
transactions (even single statements in autocommit mode). This is
so that replication from non-transactional to transactional table
and error recovery from XA to non-XA table should work as
expected. The BEGIN/COMMIT are added in log.cc. However, there is
one exception: MyISAM bypasses log.cc and writes directly to the
binlog. So if autocommit is off, master has MyISAM, and slave has
a transactional engine, then the slave will just see one long
never-ending transaction. The only way to bypass explicit
BEGIN/COMMIT in the binlog is by using a non-transactional table.
So setting AUTOCOMMIT=1 will make this work as expected.
Note: explicitly replicate AUTOCOMMIT=1 from master. We do not
assume AUTOCOMMIT=1 on slave; the slave still reads the state of
the autocommit flag as written by the master to the binlog. This
behavior may change after WL#4162 has been implemented.
