Problem reported that some bgp and ospf json commands did not return
any json output at all if the bgp/ospf instance did not exist.
Additionally, some bgp and ospf json commands did not return any json
output if the instance existed but no neighbors were defined. This
fix makes these commands more consistent in returning empty braces for
json output and issue a message if not using json output. Additionally,
made the flag "use_json" a bool to make it consistent since previously,
it had been defined as an int, char, u_char, and bool at various places.

The specific code here needs to establish an absolute order of more
specific to less specific possible matches in a prefix list. This is
indirectly checked by an assert on insertion, because the "next best"
entry is required to be consistent even when joining multiple chains
of candidates.
Unfortunately, trie_install_fn() would insert entries too far ahead in
the chain if another entry with higher sequence number was seen. This
breaks the trie and (rightfully) triggers the assertion failure on
insert.

When you startup zebra and apply a prefix list command, and then at a
later point in time start up additional daemons and then attempt to
apply the integrated-config, the prefix-list command will stop
processing after zebra.
This is because when zebra attempted to process the command, it would
notice that it already had that cli handled and print a vty warning and
then it would return CMD_WARNING. This caused the loop over all the
commands to stop and as such the command would not be sent to all the
individual daemons.
This behavior is exactly the same as it is in the 2.5.X( hell it's
upstream behavior to! ). Modify the plist command to return CMD_SUCCESS
in this case.

Prefix lists were implemented with a simple linear list that is scanned
sequentially. This is, of course, extremely inefficient as it scales by
O(n). This patch adds a trie-ish data structure that allows quickly
descending based on the prefix.
Note that the trie structure used here is designed for real-world use,
hence it uses a relatively crude fixed-size bytewise table instead of
some fancy balancing scheme. It is quite cacheline efficient.
Using real-world routeserver prefix lists, matching against a fulltable
dump:
entries before after factor
9103 63.8s .0124s 5142x
772 4.52s .0101s 445.3x
86 .445s .0098s 45.51x
7 .0379s .0099s 3.834x
2 .0136s .0095s 1.440x
1 .0084s .0095s .879x
This buys CPU with memory. Memory usage on an IXP setup with 100k
prefix list entries is an additional 4 MB on top of the 9.5 MB that it
was before.
BGP ORF prefix lists are in a separate namespace; this was previously
hooked up with a special-purpose AFI value. This is a little kludgy for

Whenever some sort of output is encountered, added a json version with
proper logic as well.
This patch implements the 'update-groups' functionality in BGP. This is a
function that can significantly improve BGP performance for Update generation
and resultant network convergence. BGP Updates are formed for "groups" of
peers and then replicated and sent out to each peer rather than being formed
for each peer. Thus major BGP operations related to outbound policy
application, adj-out maintenance and actual Update packet formation
are optimized.
BGP update-groups dynamically groups peers together based on configuration
as well as run-time criteria. Thus, it is more flexible than update-formation
based on peer-groups, which relies on operator configuration.
[Note that peer-group based update formation has been introduced into BGP by
Cumulus but is currently intended only for specific releases.]

* */*: Fix various problems flagged by Sun Studio compiler.
- '<qualifier> <storage>' obsolescent in declarations
- empty statements (';' after ALIAS definitions)
- implicit declarations (e.g printstack in lib/log.c)
- "\%" in printf string instead of "%%"
- loops that return on the first iteration (legitimately, but
compiler can't really know), e.g. bgp_routemap.c
- internal declarations which mask prototypes.
* lib/filer.c: show protocol name in filter_show()
* lib/plist.c: show protocol name in vty_show_prefix_entry()
* routemap.c: show protocol name in vty_show_route_map_entry()
* lib/vty.c: in vty_command(), show protocol name if command unknown
* zebra/zserv.c: Always provide distance fo route add
* ripd/rip_snmp.c: rip2IfConfReceive() sends values in conformance
with RFC. Also PeerDomain is now set to a STRING type.
* ripd/ripd.h: rip_redistribute_add() API includes metric and distance
* ripd/ripd.c: rip_redistribute_add() API i.e. stores metric and distance
Now allows a RIP-route to overcome a redistributed route coming
from a protocol with worse (higher) administrative distance
Metrics from redistribution are shown in show ip rip
* ripd/rip_zebra.c: adapt to the rip_redistribute_add() API, i.e.
provide distance and metric
* ripd/rip_interface.c: adapt to the rip_redistribute_add() API
* ripd/rip_routemap.c: no RMAP_COMPILE_ERROR on (metric > 16) usage
rather a CMD_WARNING, because set metric ius shared with other
protocols using larger values (such as OSPF)
The match metric action takes first external metric if present
(from redistribution) then RIP metric.
* (general) extern and static'ification of functions in code and
header.
Cleanup any definitions with unspecified arguments.
Add casts for callback assignments where the callback is defined,
typically, as passing void *, but the function being assigned has
