Comment (by neel):

 In `node_get_prim_orport()`, if a ORPort exists, the return value comes
 from `RETURN_IPV4_AP()`. It seems `RETURN_IPV4_AP()` is a macro which
 returns 0 on succes. However, there is a `node_get_prim_dirport()` which
 also calls `RETURN_IPV4_AP()` for a return value. Should I also modify
 `node_get_prim_dirport()` (remove the return value and modify functions
 depending on it to check for a `NULL` address)?
