BUG#48091 valgrind errors when slave has double not null and master has double null

Browse Source 
Backporting BUG#38173 to mysql-5.1-bugteam

The reason of  the bug was incompatibile with the master side behaviour.
INSERT query on the master is allowed to insert into a table without specifying
values of DEFAULT-less fields if sql_mode is not strict.
                  
Fixed with checking sql_mode by the sql thread to decide how to react.
Non-strict sql_mode should allow Write_rows event to complete.
                  
todo: warnings can be shown via show slave status, still this is a 
separate rather general issue how to show warnings for the slave threads.
