PROGRESS NOTES:



DESCRIPTION:

Store in binlog (and show in mysqlbinlog output) texts of statements that 
caused RBR events

This is needed for (list from Monty):
- Easier to understand why updates happened
- Would make it easier to find out where in application things went
  wrong (as you can search for exact strings)
- Allow one to filter things based on comments in the statement.

The cost of this can be that the binlog will be approximately 2x in size 
(especially insert of big blob's would be a bit painful), so this should 
be an optional feature.
