The definition of the interface commands in vtysh.c were outdated.
Currently, all daemons that call if_cmd_init() will have the "no interface
IFNAME" command and the "[no] description" commands as well, so there's
no need to define exceptions for these commands anymore.
To fix this, make extract.pl parse the if.c file so that vtysh can get the
interface commands from there automatically. Only the "interface IFNAME
[vrf NAME]" must be kept in vtysh.c because it changes the vty node and
thus needs special treatment.
Finally, make pimd and pbrd display interface descriptions on "sh run"
when they are configured.

There is no need to check for failure of a ALLOC call
as that any failure to do so will result in a assert
happening. So we can safely remove all of this code.

Don't show BFD commands with timers since it might confuse users
("show running-config" won't display timers in client daemons anymore),
but keep accepting this command from previous configurations.

When BFD timers are configured, don't show it anymore in the daemon
side. This will help us migrate the timers command from daemons to
`bfdd`.

When calling route_map_finish, every place that we do we must
first set the deletion event to NULL, or we will create an infinite
loop, if we are using the delayed route-map application code.
As such we might as well just make the route_map_finish code
do this work, as that there is really no viable alternative here
and route_map_finish should only be called on shutdown.
This fixes an infinite loop in zebra on shutdown when there
are route-maps.

Packet sending in PIM is a two step process.
1) Gather data size of next G to be packed into a packet.
2) Write data
After 1 we need to ensure that the next G to pack will actually
fit in a packet. If it does not send what we've currently written
and start a new packet to send.
Because this was a 2 step process it is important to be consistent
in what you think you have packed -vs- what you think you should.
PIM has a bug where we were considering S,G RPT Prunes for a *,G
even when the *,G was being pruned. This lead to a situation where
we were figuring a write size of more data then what we actually wrote
into a packet. This would leave a 8 byte whole of 0's in the packet
due to the way we moved pointers around.
Fix the code so that we do not attempt to consider S,G rpt prunes
for a *,G prune when figuring out how much we should write in step 1.

When we receive a IGMP report on an interface, do not create upstream
state for that request, unless we are the DR for the incoming interface.
This will prevent a interface on a LAN segment from causing traffic
to flow to itself.

In places where we do a pim_ecmp_nexthop_search, also
use pim_ecmp_nexthop_lookup instead of the single path
case of pim_nexthop_lookup.

When we are looking up a RPF with a ecmp path, there
are situations where we are failing to find a path change
because we were not considering the actual number of neighbors
we have available to us at the start of the loop.
Example:
Suppose 2 way ecmp with a neighbor on each path. We have
multiple upstreams that are strewn across both paths.
If we loose a pim neighbor on one of the paths we would
initiate a rescan of the upstreams. If the neighbor
we lost happened to be the last ecmp path we rescanned
we would not successfully find a new path and leave
the upstream stranded.
This code change looks at the number of available neighbors
that we have -vs- the number of paths we have and chooses
the smaller of the two for figuring out what to do.
There probably exist other failure scenarios as well that
I am missing here and quite frankly the current code muddies
the water between a RPF lookup failure -vs- a RPF lookup succeeded
and there are no paths. Further work is needed here imo.
Additionally this idea of a pim_ecmp_nexthop_lookup and
pim_ecmp_nexthop_search is bogus. They are the same function and
should be merged at some point in time.
