This commit is the implementation of weak multicast traceroute.
It consists of IGMP module dealing with mtrace type IGMP messages
and client program mtrace/mtracebis for initiating mtrace queries.

When PIM handles some MSDP commands, a repeated command
was causing a CMD_WARNING_CONFIG_FAILED. This should
be a CMD_WARNING. Fix the code to allow vtysh to handle
this appropriately.

When we ask PIM to do a CLI search of a random (S,G) if the
(S,G) has no RPF due to no route, let the user know about
the issue instead of crashing.

This improves code readability and also future-proofs our codebase
against new changes in the data structure used to store interfaces.
The FOR_ALL_INTERFACES_ADDRESSES macro was also moved to lib/ but
for now only babeld is using it.

This is an important optimization for users running FRR on systems with
a large number of interfaces (e.g. thousands of tunnels). Red-black
trees scale much better than sorted linked-lists and also store the
elements in an ordered way (contrary to hash tables).
This is a big patch but the interesting bits are all in lib/if.[ch].

This will allow people using grep over the command

Adds the ability to filter PIM Joins & IGMP reports on an interface.
Enabling a multicast boundary on an interface for a particular group
will prevent the interface from appearing in the group's OIL.

All the rp debugs were a mish-mash of TRACE or ZEBRA,
but the reality they were all focused on handling NHT
issues associated with the RP's. So let's create
a new debug 'debug pim nht rp' if you are having
issues with RP's.

This feature does this:
Add the ability to store the non-prefix static RP
entries into a table. Then to lookup the G to
find the RP in that table, finding the longest
prefix match across both prefix-lists and
static RP's.

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:

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

no ip pim bfd, if pim is not enabled display warning and return.

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.

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.
