In NMPlatform, the route cache will have to be extended to preserve the order or routes. A circular, doubly-linked list like kernel's "struct list_head" or CList will be used for that. This data structure is nice for certain use-cases, because the linking infrastructure can be embedded in the linked objects, which is more efficient -- but only works if the linked object is only part of one list at a time, and if the linked object is aware of the linking altogether.


Import CList [1], and use it at a few places as show-case.
