BUG#49019 Mixing self-logging eng. and regular eng. does not switch to row in mixed mode

Reading from a self-logging engine and updating a transactional engine such as Innodb
generates changes that are written to the binary log in the statement format and may
make slaves diverge. In the mixed mode, such changes should be written to the binary
log in the row format.

Note that the issue does not happen if we mix a self-logging engine and MyIsam
as this case is caught by checking the mixture of non-transactional and transactional
engines.

So, we classify a mixed statement where one reads from NDB and writes into another 
engine as unsafe:

if (multi_engine && flags_some_set & HA_HAS_OWN_BINLOGGING)
  lex->set_stmt_unsafe(LEX::BINLOG_STMT_UNSAFE_MULTIPLE_ENGINES_AND_SELF_LOGGING_ENGINE);

mysql-test/suite/rpl_ndb/r/rpl_ndb_mixed_engines_transactions.result:
  Augmented test case to check mixed statements
mysql-test/suite/rpl_ndb/t/rpl_ndb_mixed_engines_transactions.test:
  Augmented test case to check mixed statements
sql/share/errmsg-utf8.txt:
  Added ER_BINLOG_UNSAFE_MULTIPLE_ENGINES_AND_SELF_LOGGING_ENGINE
sql/sql_class.cc:
  Redefined flags' name in order to have two sets of flags: (i) flags that are checked when there
  is a write operation; (ii) flags that are checked regardless of the type of the operation.
