There's no such thing as a read-only connection. In a normal connection, you can have many attached databases. Some r/o, some r/w. To properly fix that, we also need to fix the OpenWrite opcode. Right now we are passing a name, which is the name of the table. That parameter is not used anywhere. That is also not what the SQLite opcode specifies. Same as OpenRead, the p3 register should be the database index. With that change, we can - for now - pass the index 0, which is all we support anyway, and then use that to test if we are r/o.
