Start the separation of tracking a Destination from the act
of looking it up. The cojoining of these two concepts led
to a bunch of code that had to think about both problems leading
to weird situations and code paths. Simplify the code by making
pim_ecmp_nexthop_search a static function and we only ever
call pim_ecmp_nexthop_lookup when we need to do a RPF().
pim_ecmp_nexthop_lookup will now attempt to find a stored pnc
and if it finds one it will report on the answer from it.

The current reverse logic led to this code construct
if (!pim_nexthop_lookup(...)) {
//Do something successfull
}
This is backwards and will cause logic errors when people
use this code. Fix to use true/false for success/failure.

Issue: (*,G) mroute uptime is not updated in mroute table,
after deleting and adding the RP
Root cause: When RP gets deleted or becomes not reachable, then
we un-install the entry from the kernel, but still maintains the
entry in the stack. When RP gets re-configured or becomes reachable,
"show ip mroute" shows the uptime, when the channel_oil gets created.
Fix: Introduce a new time mroute_creation in the channel_oil, gets
updated when mroute gets installed in the kernel.

Suppose we have 2 routers A and B. Both Router A and B have
the same priority of 1000. Router A is the elected DR.
Now suppose B lowers his priority to 1. He still looses the
DR election and we are not sending a hello with the new priority.
Immediately after this A's priority is also lowered to 1, it
looses the election and sends the hello. B receives this hello
and elects A as the DR( since it has the better ip address)
At this point A believes B is the DR, and B believes A is the
DR until such time that the normal hello from B is sent to A,
which if timed correctly can be a significant amount of time).
This code just causes a hello to be sent if the priority is
changed. Now both sides will be able to converge quickly

1. Source registration is skipped for SSM groups. For SSM groups mroute
is setup on the FHR when a new multicast flow is rxed; however source

On the FHR upstream-join-state is not particularly relevant as we

triggered changes to the JoinDesired macro were accidentally overwriting
the state with join info (instead of treating it as register info)

Testing Done: verified pim-register state-machine with separate and
