Reduce or eliminate use of global zebra_ns structs in a couple of netlink/kernel code paths, so that those paths can potentially be made asynch eventually. Slide netlink_talk_info into place to remove dependency on core zebra structs; add accessors for dplane context block Start init of route context from zebra core re and rn structs; start queueing and event handling for incoming route updates. Expose netlink apis that don't rely on zebra core structs; add parallel route-update code path using the dplane ctx; simplest possible event loop to process queued route' updates.
