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).

This change addresses the following :
1. Ensures zlog_debug should be under DEBUG macro check
2. Ensures zlog_err and zlog_warn wherever applicable.
3. Removed few posivite logs from fpm handling, whose frequency is high.

when a client disconnects, we iterate over the routing table to
remove any label that originated from that client. However we
were erroneously passing the route type to the function, while
it was expecting the lsp type. As a result, for example, killing
ldpd would not remove the ldp labels from the routes.
Kudos to @rwestphal for pointing me to the source of the issue.

speed interface is done 15 seconds after interface creation. during that
time, the vrf or the interface may have disappeared. to protect this,
return an error in case it is not possible to create a vrf socket or it
is not possible to get speed of an interface because of a missing
device.

User pass the string match large-community 1 exact-match from CLI.
Now route map lib has got the string as "1 exact-match". It passes the string
to call back for compilation. BGP will parse this string and came to know
that for "1" it has to do exact match. Routemap lib has to save "1" in it’s
dependency table. Here routemap is saving this as a “1 exact-match”
which is wrong. The solution is used the compiled data.

When selecting a new best route, zebra sends a redist update
when the route is installed. There are cases where redist
clients may not see that redist add - clients who are not
subscribed to the new route type, e.g. In that case, attempt
to send a redist delete for the old/previous route type.
Revised the redist delete api to accomodate both cases;
also tightened up the const-ness of a few internal redist apis.

Use the zserv_client_close hook to cleanup all MPLS labels advertised
by a zclient when it disconnects. We were doing this cleanup for
ldpd only, but now we have other daemons that are MPLS aware,
like ospfd (due to the new Segment Routing feature).

Use the route type and instance instead of the route distance
to identify MPLS FTNs. This is a more robust approach since the
routing daemons can modify the distance of their announced routes
via configuration, which can cause inconsistencies.

Do this for the following reasons:
* Improve modularity of the code by separating the decoding of the
