Subject: [PATCH] Perform significant refactoring in the core and plugin code in order to help make it easier for external developers to extend OpenDS. In particular, this is a big step towards eliminating the need for developers to reference anything in the core package, and it's also a signficant simplification to the plugin API because it helps expose which operation methods are safe to call at various points in the plugin processing.
