Make it possible to decide whether we want to initialize connections and filters together with toolcontext creation. Add "filters" and "connections" fields to struct cmd_context_initialized_parts and set these in cmd_context.initialized instance accordingly. (For now, all create_toolcontext calls do initialize connections and filters, we'll change that in subsequent patch appropriately.)
