Add signal handlers for daemon to shut down Add destroy listeners for modules and do cleanup Fix some leaks Simplify port registration in new nodes Hide some more data structures Let the node implementation take care of the reuse_buffer signal because then we can get to the graph nodes to find the destination port. Destroy modules in core cleanup. Modules should undo everything they have done. Activate the link after we negotiated format and buffers.
