Martin Hansson 2a22dc2e01 Bug#49534: multitable IGNORE update with sql_safe_updates ...

error causes debug assertion

The IGNORE option of the multiple-table UPDATE command was
not intended to suppress errors caused by the
sql_safe_updates mode. This flag will raise an error if the
execution of UPDATE does not use a key for row retrieval,
and should continue do so regardless of the IGNORE option.

However the implementation of IGNORE does not support
exceptions to the rule; it always converts errors to
warnings and cannot be extended. The Internal_error_handler
interface offers the infrastructure to handle individual
errors, making sure that the error raised by
sql_safe_updates is not silenced.

Fixed by implementing an Internal_error_handler and using it
for UPDATE IGNORE commands.
