Bug#29477: Not all fields of the target table were checked to have a default

Browse Source 
value when inserting into a view.

The mysql_prepare_insert function checks all fields of the target table that
directly or indirectly (through a view) are specified in the INSERT
statement to have a default value. This check can be skipped if the INSERT
statement doesn't mention any insert fields. In case of a view this allows
fields that aren't mentioned in the view to bypass the check.

Now fields of the target table are always checked to have a default value
when insert goes into a view.
