Query_log_event::error_code
A query can perform completely having the local var error of mysql_$query
zero, where $query in insert, update, delete, load,
and be binlogged with error_code e.g KILLED_QUERY while there is no
reason do to so.
That can happen because Query_log_event consults thd->killed flag to
evaluate error_code.
Fixed with implementing a scheme suggested and partly implemented at
time of bug@22725 work-on. error_status is cached immediatly after the
control leaves the main rows-loop and that instance always corresponds
to `error' the local of mysql_$query functions. The cached value
is passed to Query_log_event constructor, not the default thd->killed
which can be changed in between of the caching and the constructing.

sql/sql_insert.cc:
DBUG_ASSERT
The reason for the bug was that replaying of a query on slave could not be possible since its event
was recorded with the killed error. Due to the specific of handling INSERT, which per-row-while-loop is
unbreakable to killing, the query on transactional table should have not appeared in binlog unless
there was a call to a stored routine that got interrupted with killing (and then there must be an error
returned out of the loop).
The offered solution added the following rule for binlogging of INSERT that accounts the above
specifics:
For INSERT on transactional-table if the error was not set the only raised flag
is harmless and is ignored via masking out on time of creation of binlog event.
For both table types the combination of raised error and KILLED flag indicates that there
was potentially partial execution on master and consistency is under the question.
In that case the code continues to binlog an event with an appropriate killed error.
The fix relies on the specified behaviour of stored routine that must propagate the error
to the top level query handling if the thd->killed flag was raised in the routine execution.
The patch adds an arg with the default killed-status-unset value to Query_log_event::Query_log_event.
sql/log_event.cc:
killed_status as the value of thd->killed can be passed as an arg to the constructor.
if the value is different from the default the arg is set to the current thd->killed value.
A caller might need to masquerade thd->killed with THD::NOT_KILLED.
So far only mysql_insert() uses such explicit way to tell the constructor about killing status.
sql/log_event.h:
default arg to the constructor with meaning of killed status of the query.
if the arg is not explicitly provided the status of thd->killed will be snapshot
inside of the constuctor, which is potentially incorrect (see bug#27571)
sql/sql_class.h:
extending killed_state with no-state member.
sql/sql_insert.cc:
ignore the KILLED flag incl KILL_BAD_DATA when the INSERT query event
is created without an `error';
