If the user were to uncomment last line
and allow VTYSH_SHOW to be used as a non-root
account, this would allow arbitrary command completion
inside of vtysh via multiple -c ... -c .... lines

FRR when compiled with this debian packaging will cause
some issue with the system to work properly due to the
sudoers file conflicts.
So to prevent some level of stupidity, mark them as
conflicting.

During processing of Join/Prune,
for a S,G entry, current state is SGRpt, when only *,G is
received, need to clear SGRpt and add/inherit the *,G OIF to S,G so
it can forward traffic to downstream where *,G is received.
Upon receiving SGRpt prune remove the inherited *,G OIF.
From, downstream router received *,G Prune along with SGRpt
prune. Avoid sending *,G and SGRpt Prune together.
Reset upstream_del reset ifchannel to NULL.
Testing Done:
Run failed smoke test of sending data packets, trigger SPT switchover,
*,G path received SGRpt later data traffic stopped S,G ages out from LHR, sends only
*,G join to upstream, verified S,G entry inherit the OIF.
Upon receiving SGRpt deletes inherited oif and retains in SGRpt state.

Upon static IGMP configured port down igmp source info is destroyed.
Upon port up or quagga restart (if addr add) register IGMP sock with
port, source, group.

Upon pim enabled disabled, current upstreams entries rpf update callback,
needs to check if old rpf is still pim enabled otherwise do not trigger
prune towards old rpf.
Testing Done:
Verified by disabling pim enabled rpf interface and
crash is not observed upon disabling pim on rpf interface.

ip pim ecmp and ip pim ecmp rebalance configuration CLIs were
not adding to Quagga.confg or running configuration.
Added both the configuration write in Config write handler.
Testing Done: Execute configuration cli and verified running config
and Quagga.conf file containing both configuration.

During PIM Neighbor change/UP event, pim_scan_oil api
scans all channel oil to see any rpf impacted. Instead of
passing current upstream's RPF it passes current RPF as 0 and
does query to rib for nexhtop (without ECMP/Rebalance). This creates
inconsist RPF between Upstream and Channel oil.
In Channel Oil keep backward pointer to upstream DB and fetch up's
RPF and passed to channel_oil scan.
Decrement channel_oil ref_count in upstream_del when decrementing
up ref_count and it is not the last.
Created ECMP based FIB lookup API.
Testing Done:
Performed following testing on tester setup:
5 x LHR, 4 x MSDP Spines, 6 Sources each sending to 1023 groups from one of the spines.
Total send rate 8Mpps.
Test that caused problems was to reboot every device at the same time.
After fix performed 5 iterations of reboot devices and show no sign of the problem.
