Speed up get_current_state_ids
Using _simple_select_list is fairly expensive for functions that return a lot of rows and/or get called a lot. (This is because it carefully constructs a list of dicts). get_current_state_ids gets called a lot on startup and e.g. when the IRC bridge decided to send tonnes of joins/leaves (as it invalidates the cache). We therefore replace it with a custon txn function that builds up the final result dict without building up and intermediate representation.
