Previously all arguments were passed through driver.IsValid. This checked arguments against a few fundamental go types and prevented others from being passed in as arguments. The new interface driver.NamedValueChecker may be implemented by both driver.Stmt and driver.Conn. This allows this new interface to completely supersede the driver.ColumnConverter interface as it can be used for checking arguments known to a prepared statement and arbitrary query arguments. The NamedValueChecker may be skipped with driver.ErrSkip after all special cases are exhausted to use the default argument converter. In addition if driver.ErrRemoveArgument is returned the argument will not be passed to the query at all, useful for passing in driver specific per-query options. Add a canonical Out argument wrapper to be passed to OUTPUT parameters. This will unify checks that need to be written in the NameValueChecker. The statement number check is also moved to the argument converter so the NamedValueChecker may remove arguments passed to the query.
