[Maria-developers] Review request: SHOW EXPLAIN, attempt 2

Hi Sergei, Hi Sergei, Please find attached the updated combined SHOW EXPLAIN patch. I believe all of feedback from the previous review has been addressed, except for: - Request to use of dbug sync facility for testing: this is waiting for you to come up with idea about how this can be done, - Error messages: you've indicated you were not happy with the current ones but I don't have any clue what set of errors would be better.
