BUG#11758262 - 50439: MARK INSERT...SEL...ON DUP KEY UPD,REPLACE...SEL,CREATE...[IGN|REPL] SEL

Problem: The following statements can cause the slave to go out of sync 
if logged in statement format: 
INSERT IGNORE...SELECT 
INSERT ... SELECT ... ON DUPLICATE KEY UPDATE 
REPLACE ... SELECT 
UPDATE IGNORE :
CREATE ... IGNORE SELECT 
CREATE ... REPLACE SELECT  
           
Background: Since the order of the rows returned by the SELECT 
statement or otherwise may differ on master and slave, therefore
the above statements may cuase the salve to go out of sync with
the master. 
      
Fix:
Issue a warning when statements like the above are exectued and 
the bin-logging format is statement. If the logging format is mixed,
use row based logging. Marking a statement as unsafe has been 
done in the sql/sql_parse.cc instead of sql/sql_yacc.cc, because while
parsing for a token has been done we cannot be sure if the parsing
of the other tokens has been done as well.
      
Six new warning  messages has been added for each unsafe statement. 
      
binlog.binlog_unsafe.test has been updated to incoporate these additional unsafe statments.

# BUG#59338 Inconsistency in binlog for statements that don't change any rows STATEMENT SBR
# In SBR, if a statement does not fail, it is always written to the binary log,
# regardless if rows are changed or not. If there is a failure, a statement is
# only written to the binary log if a non-transactional (.e.g. MyIsam) engine
# is updated. INSERT ON DUPLICATE KEY UPDATE was not following the rule above
# and was not written to the binary log, if then engine was Innodb.
#
# In this test case, we check if INSERT ON DUPLICATE KEY UPDATE that does not
# change anything is still written to the binary log.
