	* rib.h: (struct rib) Add lock field for refcounting.
	* zserv.h: (struct zebra_t) Add a ribq workqueue to the zebra
	  'master' struct.
	* zserv.c: (zread_ipv4_add) XMALLOC then memset should be XCALLOC.
	* zebra_rib.c: Clean up refcounting of route_node, make struct rib
	  refcounted and convert rib_process to work-queue. In general,
	  rib's should be rib_addnode'd and delnode'd to route_nodes, and
	  these symmetrical functions will manage the locking of referenced
	  route_node and freeing of struct rib - rather than having users
	  manage each seperately - with much scope for bugs..
	  (newrib_free) removed and replaced with rib_lock
	  (rib_lock) new function, check state of lock and increment.
	  (rib_unlock) new function, check lock state and decrement. Free
	  struct rib if refcount hits 0, freeing struct nexthop's, as
	  newrib_free did.
	  (rib_addnode) Add RIB to route_node, locking both.
	  (rib_delnode) Delete RIB from route_node, unlocking each.
	  (rib_process) Converted to a work-queue work function.
	  Functional changes are minimal, just arguments, comments and
	  whitespace.
	  (rib_queue_add_qnode) Helper function to setup a ribq item.
	  (rib_queue_add) Helper function, same arguments as old
	  rib_process, to replace in callers of rib_process.
	  (rib_queue_qnode_del) ribq deconstructor.
	  (rib_queue_init) Create the ribq.
	  (rib_init) call rib_queue_init.
	  (remainder) Sanitise refcounting of route_node's. Convert to
	  rib_queue_add, rib_addnode and rib_delnode. Change XMALLOC/memset
	  to XCALLOC. Remove calls to nexthop_delete and nexthop_free.
