Bug #23333 stored function + non-transac table + transac table = breaks stmt-based binlog

Binlogging of the statement with a side effect like a modified non-trans table did not happen.
The artifact involved all binloggable dml queries.

Fixed with changing the binlogging conditions all over the code to exploit thd->transaction.stmt.modified_non_trans_table
introduced by the patch for bug@27417.

Multi-delete case has own specific addressed by another bug@29136. Multi-update case has been addressed by bug#27716 and
patch and will need merging.
