InnoDB specified.
            
NO_ENGINE_SUBSTITUTION added to TRADITIONAL sql mode to prevent
silent conversions from InnoDB to MyISAM in that sql mode.

A number of test case results files updated to reflect this change.
Test added to sql_mode.test that checks that TRADITIONAL really 
includes NO_ENGINE_SUBSTITUION.


mysql-test/t/ctype_utf8.test:
  This test lacked "--source include/have_innodb.inc" which meant that 
  a number of DDL statements with engine=innodb in reality were using 
  myisam. "--disable_warnings" around all such statements, meant that 
  these engine substitutions were not visible. Test case has been 
  updated to include have_innodb.inc and "--disable_warnings" have been 
  removed for the relevant DDL statements.
