This moves all install_element calls into the file where the DEFUNs are
located. This fixes several small related bugs:
- ospf6d wasn't installing a "no interface FOO" command
- zebra had a useless copy of "interface FOO"
- pimd's copy of "interface FOO" was not setting qobj_index, which means
"description LINE" commands would fail with an error
The next commit will do the actual act of making "foo_cmd" static.

RFC 2453 says (section 5.1):
"(...) For completeness, routers should also implement a receive control
switch which would determine whether to accept, RIP-1 only, RIP-2 only,
both, or none. It should also be configurable on a per-interface basis".
For the "ip rip send version" command, we don't need to implement the
"none" option because there's already the "passive-interface" command
for that.
Fixes IxANVL RIP test 16.8.

* rip_interface.c: Default for split_horizon_default differed between
rip_interface_new and rip_interface_reset, causing at least some issues
after interface events. See patchwork #604. Fix, and consolidate code.
(rip_interface_{reset,clean}) rename these to 'interface', as that's more
appropriate. Spin the ri specific bodies of these functions out to
rip_interface_{reset,clean} helpers. Factor out the overlaps, so
rip_interface_reset uses rip_interface_clean.
(rip_interface_new) just use rip_interface_reset.
* ripd.h: Update for (rip_interface_{reset,clean})
Reported by xufeng zhang, with a suggested fix on which this commit expands.
See patchwork #604. This commit addresses only the split-horizon
discrepency, issue #2. The other issue they reported, #1, is not addressed,
though suggested fix seems inappropriate.

OpenBSD doesn't support the "ifindex hack" derived from RFC 1724 which
allows an ifindex to be encoded in the imr_interface field (in_addr)
of the ip_mreq structure. OpenBSD also doesn't support the RFC3678
Protocol-Independent socket API extensions, which allows an interface
to be specified by its ifindex. With that said, in OpenBSD we still need
to specify an interface by its IP address. This patch adds an exception
in the multicast sockopt functions to handle this case.

* Each node in the routing table is changed into a list, holding
the multiple equal-cost paths.
* If one of the multiple entries gets less-preferred (greater
metric or greater distance), it will be directly deleted instead
of starting a garbage-collection timer for it.
The garbage-collection timer is started only when the last entry
in the list gets INFINITY.
* Some new functions are used to maintain the ECMP list. And hence
rip_rte_process(), rip_redistribute_add() and rip_timeout() are
significantly simplified.
* rip_zebra_ipv4_add() and rip_zebra_ipv4_delete() now can share
the common code. The common part is moved to rip_zebra_ipv4_send().

The API messages are used by zebra to exchange the interfaces, addresses,
routes and router-id information with its clients. To distinguish which
VRF the information belongs to, a new field "VRF ID" is added in the
message header. And hence the message version is increased to 3.
* The new field "VRF ID" in the message header:
Length (2 bytes)
Marker (1 byte)
Version (1 byte)
VRF ID (2 bytes, newly added)
Command (2 bytes)
- Client side:
- zclient_create_header() adds the VRF ID in the message header.
- zclient_read() extracts and validates the VRF ID from the header,
and passes the VRF ID to the callback functions registered to
the API messages.
- All relative functions are appended with a new parameter "vrf_id",
including all the callback functions.
- "vrf_id" is also added to "struct zapi_ipv4" and "struct zapi_ipv6".
Clients need to correctly set the VRF ID when using the API
functions zapi_ipv4_route() and zapi_ipv6_route().
- Till now all messages sent from a client have the default VRF ID
"0" in the header.
- The HELLO message is special, which is used as the heart-beat of
a client, and has no relation with VRF. The VRF ID in the HELLO
message header will always be 0 and ignored by zebra.
- Zebra side:
- zserv_create_header() adds the VRF ID in the message header.
- zebra_client_read() extracts and validates the VRF ID from the
header, and passes the VRF ID to the functions which process
the received messages.
- All relative functions are appended with a new parameter "vrf_id".
* Suppress the messages in a VRF which a client does not care:
Some clients may not care about the information in the VRF X, and
zebra should not send the messages in the VRF X to those clients.
Extra flags are used to indicate which VRF is registered by a client,
and a new message ZEBRA_VRF_UNREGISTER is introduced to let a client
can unregister a VRF when it does not need any information in that
VRF.
A client sends any message other than ZEBRA_VRF_UNREGISTER in a VRF
will automatically register to that VRF.
- lib/vrf:
A new utility "VRF bit-map" is provided to manage the flags for
VRFs, one bit per VRF ID.
- Use vrf_bitmap_init()/vrf_bitmap_free() to initialize/free a
bit-map;
- Use vrf_bitmap_set()/vrf_bitmap_unset() to set/unset a flag
in the given bit-map, corresponding to the given VRF ID;
- Use vrf_bitmap_check() to test whether the flag, in the given
bit-map and for the given VRF ID, is set.
- Client side:
- In "struct zclient", the following flags are changed from
"u_char" to "vrf_bitmap_t":
redist[ZEBRA_ROUTE_MAX]
default_information
These flags are extended for each VRF, and controlled by the
clients themselves (or with the help of zclient_redistribute()
and zclient_redistribute_default()).
- Zebra side:
- In "struct zserv", the following flags are changed from
"u_char" to "vrf_bitmap_t":
redist[ZEBRA_ROUTE_MAX]
redist_default
ifinfo
ridinfo
These flags are extended for each VRF, as the VRF registration
flags. They are maintained on receiving a ZEBRA_XXX_ADD or
ZEBRA_XXX_DELETE message.
When sending an interface/address/route/router-id message in
a VRF to a client, if the corresponding VRF registration flag
is not set, this message will not be dropped by zebra.
- A new function zread_vrf_unregister() is introduced to process
the new command ZEBRA_VRF_UNREGISTER. All the VRF registration
flags are cleared for the requested VRF.
Those clients, who support only the default VRF, will never receive
a message in a non-default VRF, thanks to the filter in zebra.
* New callback for the event of successful connection to zebra:
- zclient_start() is splitted, keeping only the code of connecting
to zebra.
- Now zclient_init()=>zclient_connect()=>zclient_start() operations
are purely dealing with the connection to zbera.
- Once zebra is successfully connected, at the end of zclient_start(),
a new callback is used to inform the client about connection.
- Till now, in the callback of connect-to-zebra event, all clients
send messages to zebra to request the router-id/interface/routes
information in the default VRF.
Of corse in future the client can do anything it wants in this
callback. For example, it may send requests for both default VRF
and some non-default VRFs.

Later, an interface will belong to a specific VRF, and the interface
initialization will be a part of the VRF initialization. So now call
if_init() from vrf_init(), and if_terminate() from vrf_terminate().
Daemons have the according changes:
- if if_init() was called or "iflist" was initialized, now call
vrf_init() instead;
- if if_terminate() was called or "iflist" was destroyed, now call
vrf_terminate() instead.

* if.h: (struct connected) Add new ZEBRA_IFA_PEER flag indicating
whether a peer address has been configured. Comment now shows
the new interpretation of the destination addr: if ZEBRA_IFA_PEER
is set, then it must contain the destination address, otherwise
it may contain the broadcast address or be NULL.
(CONNECTED_DEST_HOST,CONNECTED_POINTOPOINT_HOST) Remove obsolete
macros that were specific to IPv4 and not fully general.
(CONNECTED_PEER) New macro to check ZEBRA_IFA_PEER flag.
(CONNECTED_PREFIX) New macro giving the prefix to insert into
the RIB: if CONNECTED_PEER, then use the destination (peer) address,
else use the address field.
(CONNECTED_ID) New macro to come up with an identifying address
for the struct connected.
* if.c: (if_lookup_address, connected_lookup_address) Streamline
logic with new CONNECTED_PREFIX macro.
* prefix.h: (PREFIX_COPY_IPV4, PREFIX_COPY_IPV6) New macros
for better performance than the general prefix_copy function.
* zclient.c: (zebra_interface_address_read) For non-null destination
addresses, set prefixlen to equal the address prefixlen. This
is needed to get the new CONNECTED_PREFIX macro to work properly.
* connected.c: (connected_up_ipv4, connected_down_ipv4,
connected_up_ipv6, connected_down_ipv6) Simplify logic using the
new CONNECTED_PREFIX macro.
(connected_add_ipv4) Set prefixlen in destination addresses (required
by the CONNECTED_PREFIX macro). Use CONNECTED_PEER macro instead
of testing for IFF_POINTOPOINT. Delete invalid warning message.
Warn about cases where the ZEBRA_IFA_PEER is set but no
destination address has been supplied (and turn off the flag).
(connected_add_ipv6) Add new flags argument so callers may set
the ZEBRA_IFA_PEER flag. If peer/broadcast address satisfies
IN6_IS_ADDR_UNSPECIFIED, then reject it with a warning.
Set prefixlen in destination address so CONNECTED_PREFIX will work.
* connected.h: (connected_add_ipv6) Add new flags argument so
callers may set the ZEBRA_IFA_PEER flag.
* interface.c: (connected_dump_vty) Use CONNECTED_PEER macro
to decide whether the destination address is a peer or broadcast
address (instead of checking IFF_BROADCAST and IFF_POINTOPOINT).
* if_ioctl.c: (if_getaddrs) Instead of setting a peer address
only when the IFF_POINTOPOINT is set, we now accept a peer
address whenever it is available and not the same as the local
address. Otherwise (no peer address assigned), we check
for a broadcast address (regardless of the IFF_BROADCAST flag).
And must now pass a flags value of ZEBRA_IFA_PEER to
connected_add_ipv4 when a peer address is assigned.
The same new logic is used with the IPv6 code as well (and we
pass the new flags argument to connected_add_ipv6).
(if_get_addr) Do not bother to check IFF_POINTOPOINT: just
issue the SIOCGIFDSTADDR ioctl and see if we get back
a peer address not matching the local address (and set
the ZEBRA_IFA_PEER in that case). If there's no peer address,
try to grab SIOCGIFBRDADDR regardless of whether IFF_BROADCAST is set.
* if_ioctl_solaris.c: (if_get_addr) Just try the SIOCGLIFDSTADDR ioctl
without bothering to check the IFF_POINTOPOINT flag. And if
no peer address was found, just try the SIOCGLIFBRDADDR ioctl
without checking the IFF_BROADCAST flag. Call connected_add_ipv4
and connected_add_ipv6 with appropriate flags.
* if_proc.c: (ifaddr_proc_ipv6) Must pass new flags argument to
connected_add_ipv6.
* kernel_socket.c: (ifam_read) Must pass new flags argument to
connected_add_ipv6.
* rt_netlink.c: (netlink_interface_addr) Copy logic from iproute2
to determine local and possible peer address (so there's no longer
a test for IFF_POINTOPOINT). Set ZEBRA_IFA_PEER flag appropriately.
Pass new flags argument to connected_add_ipv6.
(netlink_address) Test !CONNECTED_PEER instead of if_is_broadcast
to determine whether the connected destination address is a
broadcast address.
* bgp_nexthop.c: (bgp_connected_add, bgp_connected_delete)
Simplify logic by using new CONNECTED_PREFIX macro.
* ospf_interface.c: (ospf_if_is_configured, ospf_if_lookup_by_prefix,
ospf_if_lookup_recv_if) Simplify logic using new CONNECTED_PREFIX
macro.
* ospf_lsa.c: (lsa_link_ptop_set) Using the new CONNECTED_PREFIX
macro, both options collapse into the same code.
* ospf_snmp.c: (ospf_snmp_if_update) Simplify logic using new
CONNECTED_ID macro.
(ospf_snmp_is_if_have_addr) Simplify logic using new CONNECTED_PREFIX
macro.
* ospf_vty.c: (show_ip_ospf_interface_sub) Use new CONNECTED_PEER macro
instead of testing the IFF_POINTOPOINT flag.
* ospfd.c: (ospf_network_match_iface) Use new CONNECTED_PEER macro
instead of testing with if_is_pointopoint. And add commented-out
code to implement alternative (in my opinion) more elegant behavior
that has no special-case treatment for PtP addresses.
(ospf_network_run) Use new CONNECTED_ID macro to simplify logic.
* rip_interface.c: (rip_interface_multicast_set) Use new CONNECTED_ID
macro to simplify logic.
(rip_request_interface_send) Fix minor bug: ipv4_broadcast_addr does
not give a useful result if prefixlen is 32 (we require a peer
address in such cases).
* ripd.c: (rip_update_interface) Fix same bug as above.

(from redistribution) then RIP metric.

* ripd.c: (general) Fix previous commit, broke multicast bind and
hence setting of source port, which broke communication with
non-borken ripd. Fix removes more stuff from rip_interface.c
than it adds to ripd.c ;)
(rip_create_socket) the to argument really is a from argument,
rename it. Set the source port to RIP port unconditionally, it's
required.
(rip_send_packet) Set from address correctly for multicast.
(rip_output_process) trivial: num can be BSS specified, rather
than in body.
* rip_interface.c: (rip_interface_multicast_set) strip out
redundant stuff related to bind, which rip_create_socket does.
Just make it set the multicast socket option, as per the
interface concerned, no more.
