This code is not returned anywhere in the system as that bgp
is by default multiple-instance 'only' now. So remove
the last remaining bits of it from the code base.
Remove BGP_ERR_MULTIPLE_INSTANCE_USED too.
Make bgp_get explicitly return BGP_SUCCESS
instead of 0.
Remove the multi-instance error code too.

Problem reported with "clear bgp l2vpn evpn * soft" clearing the
wrong afi/safi (cleared ipv6 unicast instead). Determined that
the calling function used the argv_find_and_parse_afi/safi routines
to determine the correct afi/safi to pass on. Since l2vpn/evpn were
missing from the lookup, the command defaulted to ipv6 unicast. This
fix just adds that afi/safi to the lookup routine.

Problem reported with deleting the default BGP instance where there
are vrf instances that depend on it (like l2vpn evpn vrfs). Since
importing for vrf route-leaking also requires the existence of the
default instance, disallowing deleting the BGP default instance if

Currently, as part of bgp clear soft inboud and outbound we don't handle
l2vpn evpn. Now clearing soft for all supported afi safi.
One of the examples where this was a problem -
On applying graceful-shutdown, bgp clear soft inboud and outbound don't
handle AFI L2VPN and SAFI EVPN. Gshut gets applied to EVPN Type 5 routes
by asking peer to refresh the routes (provided we have config - "advertise
ipv4/ipv6 unicast" as part of l2vpn evpn) but is not applied to type 2
and type 3 EVP routes. This fix takes care of l2vpn evpn type2 and type3
routes being readvertised with gshut community.
This fix also fixes similar issues related to following where bgp clear
soft is requred for l2vpn evpn -
-config bgp cluster-id
-config bgp client-to-client reflection
-config bgp default local-preference
-config bgp route-reflector allow-outbound-policy
-config bgp disable-ebgp-connected-route-check

-With gshut configured on all BGP VRFs (operator has to know about the
auto-created BGP VRFs - we do show them in show commands - and turn on
graceful-shutdown in all of them.
-We announce all EVPN routes (type-2, type-3 and type-5) with GSHUT and
we mark IPv4/IPv6 routes in a VRF that are based on received EVPN type-2
or type-5 routes with local pref 0.
-On the receiver side, when EVPN routes are received with GSHUT, the
correct handling takes place (to treat them with local preference 0, and
hence not select them)
-When the gshut configuration is removed on all BGP VRFs, we re-announce
all of our EVPN routes without GSHUT and receiver does the appropriate
thing. Also, we no longer mark EVPN-based IPv4/IPv6 routes with local
pref 0.

In the above output, the peers count displays as 5 but the actual peer count is 3, i.e.. 3 neighbors are activated in ipv6 unicast address family.
Displayed peer count (5) is the number of the neighbors activated in a BGP instance.
Fix : Now the peers count displays the number of neighbors activated per afi/safi.

Found in testing that in a certain sequence, a neighbor's peer-group
membership would be lost. This fix resolves that issue. Additionally
found that "no neighbor swp1 remote-as 2" would sometimes leave the
config with "neighbor swp1 remote-as 0" rather than removing from the
config. That one is also resolved.
