  BUG#11758263 50440: MARK UNORDERED UPDATE WITH AUTOINC UNSAFE

  Problem: Statements that write to tables with auto_increment columns

           based on the selection from another table, may lead to master

           and slave going out of sync, as the order in which the rows

           are retrieved from the table may differ on master and slave.

  Solution: We mark writing to a table with auto_increment table

            based on the rows selected from another table as unsafe. This

            will cause the execution of such statements to throw a warning

            and forces the statement to be logged in ROW if the logging

            format is mixed. 

  Changes:

         1. All the statements that writes to a table with auto_increment 

            column(s) based on the rows fetched from another table, will now

            be unsafe.

         2. CREATE TABLE with SELECT will now be unsafe.

INSERT table_with_autoinc SELECT NULL, * FROM another_table;
