==================
valgrind shows memleaks in rp_table, when pimd shuts down gracefully.

Fix:
====
rp_info is allocated in pim_rp_init API. rp_info pointer is present
in rp_list and rp_table. In rp_list cleanup, the memory for rp_info
gets freed. rp_table clean up should be done first and then rp_list.

Problem:
S,G entry has iif = oif in FHR is LHR case.
Setup:-
R11-----R2----R4
R11 :- FHR and LHR
R2 :- RP
R4 :- LHR
Issue :-
1) shut mapped interface in R11
2) wait for 5 min
3) do FRR restart
5) No shut of mapped interface
OIL is added for local interface also where OIL is same as IIF
and duplicate traffic observed on R4 receives in Ixia
RCA:
pim_ifchannel_local_membership_add adds inherited oif from starg when iif for
SG is unavailable.
When rpf for that SG resolves to this inherited oif from starg, iif is also in oif.
This results in dup traffic.
Fix:
If iif is not available, do not inherit from starg.

frrscript_load now loads a function instead of a file, so frrscript_unload
should be renamed since it does not unload a function.

There is some rather heavy error checking logic in frrscript_call. Normally
I'd put this in the _frrscript_call function, but the error checking needs
to happen before the encoders/decoders in the macro are called.
The error checking looks messy but its really just nested ternary
expressions insite a larger statement expression.

Instead of 1 frrscript : 1 lua state, it is changed to 1 : N.
The states are hashed with their function names.

Add a bit of code to allow for auto-completion of the community
alias command when attempting to use it for show commands.
example:
eva(config)# bgp community alias 11:22 FOO
eva(config)# end
eva# show bgp ipv4 uni alias
ALIAS_NAME BGP community alias
FOO

- Remove incorrect requirement for `service integrated-vtysh-config`
when producing a delta.
- Add `--test-reset` option which suppresses non-parseable lines from the
produced delta
- Use new features in common_config.py

At some point we broke the ifp pointer for nhe->ifp such
that it was pointing to an interface even in groups/recurisve
instances.
Add checks here to make it again so that we only set the ifp
pointer if it is a fully resolved singleton NHE.

In the reachability code we auto pass back the fully resolved
nexthops. Modify the ZEBRA_IPV4_NEXTHOP_LOOKUP_MRIB code
to do the exact same thing so that the zclient_lookup_nexthop
code does not need to recursively look for the data that
zebra already has.
