Add the rib_dest_t structure to hold per-prefix state in the routing
information base. This gives us an appropriate place to maintain the
queueing state of a route_node. Queuing state was previously being
stored on the first rib in the list of ribs hanging off the
route_node.
* zebra/rib.h
- Add new structure rib_dest_t.
- Remove the rn_status field from 'struct rib', it is no longer
required.
- Add macros (RNODE_FOREACH_RIB, RNODE_FOREACH_RIB_SAFE) for
walking all 'struct ribs' corresponding to a route_node. These
hide the fact that there is an intermediate rib_dest_t
structure.
- Add a few utility inlines to go between a rib_dest_t and
associated structures.
* zebra/zebra_rib.c
- rib_link()/rib_unlink()
Tweak for new behavior, where the 'info' pointer of a route_node
points to a rib_dest_t. The list of ribs for a prefix now hangs
off of the dest.
Change the way we ref count route_nodes. We now hold a single
ref count on a route_node if there is a corresponding
rib_dest_t.
- Maintain the queuing state of a route_node on the flags field of
the rib_dest_t.
- Add the rib_gc_dest() function, which deletes a rib_dest_t if it
is no longer required. A rib_dest_t can be deleted iff there are
no struct ribs hanging off of it.
- Call rib_gc_dest() any time we unlink a rib from the
rib_dest_t. Currently we only need to call it once, just before
we return from rib_process().
* zebra/{redistribute,zebra_rib,zebra_snmp,zebra_vty}.c
Use new macros to walk over route_node ribs.
* lib/memtypes.c
Add memory type for rib_dest_t.

Most table handlers do not expect to be given an OID whose prefix is
outside what they can handle. This is not a problem with the SMUX
implementation since it always correct the OID such that the prefix
matches. However, this is not the case for the AgentX
implementation. A new function, smux_header_table() is used to do this
normalization.

NetSNMP is the only SNMP implementation for Quagga. We don't need two
different symbols.
