Description:
handler::start_bulk_insert() is declared as a void function. However, storage engines doing complex setup work may wish to signal an error to the caller to indicate that subsequent writes cannot be performed.

How to repeat:
Look at definition in handler.h

Suggested fix:
The API and (handler::ha_start_bulk_insert()) should return an int.

handler::start_bulk_insert() is only a hint - if a storage engine cannot do it, it just doesn't do it and MySQL will insert rows without bulk insert optimization.
