zebra: maintain the router-id per VRF

A router may need different identifier among the VRFs. So move the
maintenance of router-id per VRF.

* rib.h:

  Move the previous global variables in router-id.c into the
  "struct zebra_vrf":
  - struct list _rid_all_sorted_list/*rid_all_sorted_list
  - struct list _rid_lo_sorted_list/*rid_lo_sorted_list
  - struct prefix rid_user_assigned

* router-id.c/router-id.h:

  A new parameter "vrf_id" is added to all the router-id APIs.
  Their operations are done only within the specified VRF.

  A new command "router-id A.B.C.D vrf N" is added to allow
  manual router-id for any VRF.

  The old router_id_init() function is splitted into two:
  - router_id_cmd_init(): it only installs the commands
  - router_id_init(): this new one initializes the variables for
                      a specified VRF

* zebra_rib.c: Add new functions zebra_vrf_get/lookup() called
               from router-id.c.

* main.c: Replace router_id_init() with router_id_cmd_init() and
          call the new router_id_init() in zebra_vrf_new().
