c67d5a4a25
This patch modifies the queues code to use manually instantiated configs rather than the global config. This will allow for more flexibility in configuring components. For example, the up-and-coming sharding feature can construct configs based on the shard catalog rather than the local INI file. Also, this change will make testing easier. Also in this patch, the SQLite driver schema was consolidated into one place in preparation for the sharding patch. With this change, controllers can be instantiated and used independently, since all the tables are set up when the driver is loaded, not in a piecemeal fashion as before.
