BUG#26395: if crash during autocommit update to transactional table on master, slave fails

Now, every transaction (including autocommit transactions) starts with
a BEGIN and ends with a COMMIT/ROLLBACK in the binlog.
Added a test case, and updated lots of test case result files.

sql/log.cc:
   - Always write BEGIN and COMMIT around statements, even in autocommit
     mode.
   - Added comments for binlog_commit and binlog_rollback.
sql/log_event.cc:
  Added debug trigger to avoid writing xid events to the binlog.

  Results for new test case

--echo ==== Test 2: Master crash before writing XID event on XA engine ====
# We now want to test the following scenario, to verify that BUG#26395
# has been fixed:
# "master and slave have a transactional table that uses XA. Master
# has AUTOCOMMIT on and executes a statement (in this case an
# INSERT). Master crashes just before writing the XID event."
# In this scenario, master will roll back, so slave should not execute
# the statement, and slave should roll back later when master is
# restarted.
# However, we the master to be alive so that we are sure it replicates
# the statement to the slave. So in the test case, we must therefore
# not crash the master. Instead, we fake the crash by just not writing
# the XID event to the binlog. This is done by the
# --debug=d,do_not_write_xid flag in the .opt file.
# So, unlike if the master had crashed, the master *will* execute the
# statement. But the slave should not execute it. Hence, after the
# first test is executed, the expected result on master is a table
# with one row, and on slave a table with no rows.
# To simulate the slave correctly, we wait until everything up to the
# XID is replicated. We cannot sync_slave_with_master, because that
# would wait for the transaction to end. Instead, we wait for
# "sufficiently long time". Then we stop the slave.
# Note: since this puts the master binlog in an inconsistent state,
# this should be the last test of the file.

IMPLEMENTATION
- To support transaction over replication, we wrap the transaction
with BEGIN/COMMIT or BEGIN/ROLLBACK in the binary log.
We want to write a BEGIN/ROLLBACK block when a non-transactional table
was updated in a transaction which was rolled back. This is to ensure
that the same updates are run on the slave.
If a transaction that only involves transactional tables is
rolled back, we do not binlog it. However, we write a
BEGIN/ROLLBACK block when a non-transactional table was updated
in a transaction which was rolled back. This is to ensure that
the same updates are run on the slave.
