This patch lets the netlink sockets work per VRF. * The definition of "struct nlsock" is moved into zebra/rib.h. * The previous global variables "netlink" and "netlink_cmd" now become the members of "struct zebra_vrf", and are initialized in zebra_vrf_alloc(). * All relative functions now work for a specific VRF, by adding a new parameter which specifies the working VRF, except those functions in which the VRF ID can be obtained from the interface. * kernel_init(), interface_list() and route_read() are now also working per VRF, and moved from main() to zebra_vrf_enable(). * A new function kernel_terminate() is added to release the netlink sockets. It is called from zebra_vrf_disable(). * Correct VRF ID, instead of the previous VRF_DEFAULT, are now passed to the functions of processing interfaces or route entries.
