[jdbc-driver] Array support in query result:

```java
import acolyte.RowLists;
import acolyte.ImmutableArray;

// List of row with 1 column,
// whose type is array of string
RowLists.rowList1(java.sql.Array.class).
  append(ImmutableArray.getInstance(String.class,
    new String[] { "Ab", "Cd", "Ef" }));
```
