The commit '19b807c pimd: Allow the keepalive time to be per vrf.'
is missing some data. Probably as a result of the indentation
and I accidently dropped it.

pim is vrf aware and the interface based line for vrf's was
not being started with a vrf_frame as the non interface
based line was.

Using the previously-added vty_frame() support, this gets rid of all the
pointless empty "interface XYZ" blocks that get added for any interface
that shows up in the system (e.g. dummys, tunnels, etc.)

Specifically, gcc 4.2.1 on OpenBSD 6.0 warns about these; they're bogus
(gcc 4.2, being rather old, isn't quite as "intelligent" as newer
versions; the newer ones apply more logic and less warnings.)

1) Clean up display of S,GRPt prune state to be more meaningful
2) Upon receipt of a S,GRPt prune make sure we transition to
the correct state
3) Upon loss of a S,GRPt prune make sure we transition to
the correct state as well as immediately send a *,G
join upstream to propagate the loss of the prune.
4) Removal of a weird S,G state being installed upon
loss of a S,G RPt prune.

This could happen if routing isn't up yet but the command did take so we
should exit 0 here. Testing:
root@cel-redxp-10[frr-dwalton76]# vtysh -c 'conf t' -c' ip pim rp
11.11.11.11'
% No Path to RP address specified: 11.11.11.11

There exists a path for ifchannel creation that if a S,G
fails to create and a corresponding *,G ifchannel is there,
the S,G will be deleted but we were leaving the S,G in the
*,G ifchannel sources list. Remove from the list in this case

BFD replay for all interfaces was only considering VRF_DEFAULT interface
list.
The change will walk all VRFs, interface list per VRF to register pim
neighbor with BFD.

Upon frr restart vtysh replays pim bfd configuration
cli before pim sm command, this results in failure
of pim bfd config on the VIF as it is not pim enabled yet.
Inside pim bfd configuration, call to create PIM vif
handler if it is not created yet.
no ip pim bfd, if pim is not enabled display warning and return.

This does three things:
1) When we get a RPF_FAILURE, remove the mroute associated
with it.
-> This way when the RPF comes back we can just add the
mroute in as part of the normal scanning process.
2) When we do a ecmp_nexthop_search return 1 when we found
something we can use.
3) Ignore output from pim_update_rp_nh
-> When we do a ecmp_nexthop_search ignore the return
code and do not attempt to gather it up to return
to the calling function. It is just ignored
and we were not taking into account the what of
multiple RP's we were looking at.

If a single S,G is being deleted because the keepalive
timer has timed out, Send a *,G join upstream to clear
the S,G RPT prune bit.

The secondary address list was being added/removed as
we went. I see no reason to have special bookkeeping
for this list. Just add it on interface startup and
then remove it on deletion. Removes some
very specialized coding that was saving a very small
amount of space.

There are situations where we receive a *,G with
a S,G,RPT Prune embedded where we do not actually
have any S,G yet(MSDP with multiple RP's with the
same address). As such since we only need to
lookup the S,G ifchannel once, do it after
the recv_prune.

When a interface is flapped we were leaking some memory
associated with link lists. Especially in the jp_agg
code. If your network was/is stable and you are not
running at any scale you probably would not see this
as impactful at all.

The channel_oil has a back pointer(up) to the upstream data structure.
If we are planning on keeping the channel oil (due to ref count issues)
longer than keeping the upstream, when we delete the upstream we were
not clearing the back pointer to up. This would result in a situation
where if that memory has started to be used again it will cause a
crash and other fun things.

This patch does two things:
1) Converts the pim_ifp->ifchannel_list to a pim_ifp->ifchannel_rb
2) Removes the hashing to use the RB RB_FIND instead.

Remove the redundant information in pim_ifp->pim_ifchannel_list
just call it pim_ifp->ifchannel_list
Signed-off-by: Donald Sharp <sharpd@cumulusnetworks.com>
The pim->ifchannel_list can be duplicated by iterating
over each vrf and then over each pim_ifp->pim_ifchannel_list
Since list handling is taking allot of time at scale
convert over to using this value.
Additionally clean up pim_cmd.c to have helper functions
to handle the actual encoding of data for output.

The NHT upstream list at scale is horribly inefficient due to keeping
a sorted list of upstream entries. The attempting to find
the upstream and the insertion of it into the upstream_list
was consuming a large amount of cpu cycles.
Convert to a hash, allow add/deletions to effectively become
O(1) events.
