Allows you to run daemons under valgrind integrated with gdb. When daemons are
run with the ``--gdb-daemons/--gdb-routers`` options they will be wired up to
valgrind using vgdb (valgrind tool) so gdb will stop when valgrind errors are
encountered.

This is addressing remaining places returning
empty dict, earlier PR-13214 addressed few places.
Code has been changed to return {} for all the evpn clis
when evpn is disabled or no entry available.
```
cumulus@r2:mgmt:~$ sudo vtysh -c "show evpn json"
cumulus@r2:mgmt:~$
```
After Fix:-
```
cumulus@r1:mgmt:~$ sudo vtysh -c "show evpn json"
{
}

Modify empty json object to take input obj
instead of allocating always one.
There are situation where in error condition or no data
case print empty json (`{}`) with already allocated

Currently in the single nexthop case w/ evpn sending
down via the FPM the encap type is not being set
for the nexthop.
This looks like the result of some code reorg for the
nexthop happened but the fpm failed to be accounted for.
Let's just move the encap type encoding to where it
will happen.

It's been for a while disabled by default, but this seems reasonable to flip it.
We had `bgp enforce-first-as` as a global BGP knob to enable/disable this
behavior globally, later we introduced `enforce-first-as` per neighbor, with disabled
by default. Now let's enable this by default by bringing a global `bgp enforce-first-as`
command back.

It's tested above, and was just copied from extended-nexthop as an example
which is broken too.

extended-nexthop capability can't be unset to interface-based peers.
Anyway, this is always silently ignored:
```
✖ [test] peer\capability extended-nexthop
► prepare: initialize bgp test environment
► case 01: set peer-flag [capability extended-nexthop] on [IP-TEST]
► error: execution of command [no neighbor IP-TEST capability extended-nexthop] has failed with code [13]

https://www.rfc-editor.org/rfc/rfc5340.html#page-37 states:
If the interface type is point-
to-multipoint or the interface is in the state Loopback, the
global scope IPv6 addresses associated with the interface (if any)
are copied into the intra-area-prefix-LSA with the PrefixOptions
LA-bit set, the PrefixLength set to 128, and the metric set to 0.

In zebra, the import check table and the nexthop check tables
were combined. This leaves an issue where when bgp happens
to have a tracked address in both the import check table
and the nexthop track table that are the same address.
When the the item is removed from one table the call
to remove it from zebra removes tracking for the other
table.
Combine the two tables together and keep track where
they came from for processing in bgpd.

There is no command to choose to send or not the bgp4-mibv2 traps.
Since the MIB bgp4-mibv2 notification are redundant with MIB RFC4273
we added a command:
- [no] bgp snmp traps bgp4-mibv2
By default, the bgp4-mibv2 traps will be disabled, to prevent from
redundancy.

This commit add the support of traps for bgp4-mibv2.
It is conformant to draft-ietf-idr-bgp4-mibv2-11.
The following traps are supported:
- bgp4V2EstablishedNotification
- bgp4V2BackwardTransitionNotification

There is no cli command to prevent the router to send traps
implemented in the rfc4273. If not done, when introducing
the traps from bgp4v2mib, traps will be send for each of
the two mibs: there will be redundancy in the sent information.
Add a new command:
- [no] bgp snmp traps rfc4273
Using this command will allow or not the notification of
the following traps:
- bgpEstablishedNotification
- bgpBackwardTransNotification

If we send a crafted BGP UPDATE message without mandatory attributes, we do
not check if the length of the path attributes is zero or not. We only check
if attr->flag is at least set or not. Imagine we send only unknown transit
attribute, then attr->flag is always 0. Also, this is true only if graceful-restart
capability is received.
A crash:
