The MLAG component on the switch is expected to provide some
properties (such as peerlink-rif) to bootstrap the anycast-VTEP
functionality. The final interface for this is being defined as
a part of the pim-mlag functionality.
This commit provides a hidden command to test the anycast-VTEP
functionality independent of the MLAG component.

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.
Signed-off-by: Donald Sharp <sharpd@cumulusnetworks.com>
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

Add a test command to pim that allows you to reset the keepalive timer
for an upstream to it's max value. This is to allow purposeful testing
of cleanup code in pim, by forcing the keeaplive timer to expire later.

Issue: Configure "ip pim rp x.x.x.x 225.0.0.0/4".
Show running config shows "ip pim rp x.x.x.x 224.0.0.0/4"
This is mis-leading.
Root-cause: Internally 225.0.0.0/4 is getting converted to
224.0.0.0/4 group mask, since the prefix length is 4.
Fix: Restrict the user to configure inconsistent group address
mask by throughing a cli error "Inconsistent address and mask".
