Remove implicit conversion using `to_int` method.
The ISO standard does not include implicit type conversion using
`to_int`. This implicit conversion often causes vulnerability.
There will be no more attacks like #4120.
In addition, we have added internal convenience method `__to_int` which
does type check and conversion (from floats).
