Add reset/check for query call count

Whenever a query is executed without the db_return method and it is a
select query, then it is counted and if it is over a max value it will
return false and terminate.

With those functions that counter value can be checked and reset.

To be used carefully. It is recommended to rather make often called
queries with the same values prepare/execute style instead of resetting
the count.
