Comment:

 Revised plan and status (~~strikethrough~~ means "done"):

  * ~~Add node_t as a wrapper around routerinfo_t, and routerstatus_t. A
 node_t is "A node we could use in a circuit."~~
  * ~~Have node_ts exist whenever we have a routerstatus_t in our favored
 consensus, or a routerinfo_t.~~
  * ~~Move mutable flags and other fields from routerinfo_t into node_t.~~
    * DO NOT move document-management flags from routerinfo_t into node_t
  * Make is_foo flags in routerstatus_t as immutable as we can.
    * ~~identity what changes~~
    * Make it not change.  (It's just is_running!)
  * When making decisions about what nodes to use, base them on node_t.
 This should simplify the choose-a-node code a little.
    * ~~Change the code to use node_t~~
    * Make it all compile (doing now)
    * Implement missing node-based functions
      * Misc glue
      * Families
      * Policies
  * Add a microdesc_t backend for node_t. If we've designed it right, this
 is easy. (Doing as I go along.)


 If you want to kibbitz, have a look at branch "nodes" in my public.  I
 will rebase it a lot, though, so do not get too attached to it.  No, it
 does not compile atm.
