      Fix for Bug#12652873 - 61392: CONTINUE HANDLER FOR NOT FOUND BEING
      TRIGGERED FROM INTERNAL STORED FUNCTION.
      
      The problem was that RETURN statement in stored programs did not
      clear the Diagnostics Area, as it should have done according to
      the SQL Standard.
      
      The user-visible problem was that in some cases an SQL-condition,
      raised in the nested function call, would be visible in the outer
      scope, which in turn would lead to incorrect handler activation.
      
      The fix is to clear the Diagnostics Area before executing RETURN
      statement.
      
      Note, that after the patch, there is no way to throw an SQL-warning
      out of a stored function. From the user's view point, he/she will not
      get any warning, even if there were warnings, raised during
      the function execution.
      
      This change is backward incompatible, but it makes the behaviour of
      stored programs more in line with The Standard.
