Since DDL is prohibited inside a transaction, this patch
prohibits trigger creation and drop inside a transaction.
This was done by adding dummy trigger on replace into
_trigger space. This trigger only check if this not multistatement
transaction. Also, make assert that schema cokie wasn't
changed during transaction rollback if any.
Testsuite updated as well.
Closes #3239
