Problem reported that when a "neighbor x.x.x.x route-map FOO in"
set a next-hop value, that modified next-hop value was also sent
to eBGP peers. This is incorrect since bgp is expected to set
next-hop to self when sending to eBGP peers unless third party
next-hop on a shared segment is true. This fix modifies the
behavior to stop sending the modified next-hop to eBGP peers
if the route-map was applied inbound on another peer.

the for (ALL_LSDB...) macro was iterating over lsa,
when lsa had just been freed in these functions.
Remove the macro and make the adjustments saving lsa_next

the if_lookup_by_name_per_ns keeps a lock on the node where the
searched ifp is stored. Then this node can not be freed even if
the ifp is removed from the node. Just add the missing unlock
(as for the if_lookup_by_index_per_ns lookup function)

Current autocompletion works only for simple "vrf NAME" case.
This commit expands it also for the following cases:
- "nexthop-vrf NAME" in staticd
- usage of $varname in many daemons
All daemons are updated to use single varname "$vrf_name".

When a VxLAN interface comes up new vni up event is sent
to bgpd, which triggers bgpd to sync advertise-svi-macip
to zebra. At this point, vni is present but the associated
SVI may not be present.
When SVI comes up, vni add event sent to bgpd (with associated
vrf update). Bgpd already has vni present so
advertise-svi-macip is not synced to Zebra.
To fix,
When advertise-svi-macip flag is synced first time, cache it in
zebra context even though vni associated SVI is not present.
when SVI comes up, interface address add event triggers
new MAC-IP route add to bgpd.
Ticket:CM-26038
Reviewed By:CCR-9254
Testing Done:
Validated via running a sequence of steps in symmetric
routing topology.
- Enable advertise-svi-macip at l2vni level under bgp default
instance (afi/safi, l2vpn/evpn)
- Flap l2vni associated SVI interface.
- Check the output of 'show bgp l2vpn evpn route' command for
MAC-IP route of the SVI's (MAC and IP address).
