zebra: maintain RTADV per VRF
This moves the global variable "rtadv" into the "struct zebra_vrf",
so that RTADV feature can work per VRF.
* rtadv.c/rtadv.h:
Add a proper parameter to the functions so that the entity of the
"struct zebra_vrf" and interfaces can be obtained from the specified
VRF.
The old rtadv_init() is splitted into:
- rtadv_cmd_init(): it installs the RTADV commands; is called from
main();
- new rtadv_init(): it creates the socket; is called from
zebra_vrf_enable().
rtadv_terminate() is added to stop the threads, close the socket and
clear the counters. It is called from zebra_vrf_disable().
rtadv_make_socket() now calls vrf_socket() to create a socket in
the VRF.
* interface.h and rib.h: define the macro RTADV.
* main.c: according changes, refer to rtadv.c.
