bgpd: uninstall type-5 routes from vrf
When we receive an MP_UNREACH,
we try to uninstall routes from the VRF and the VNI.
The route-node in the VRF corresponds
to the ip prefix formed from EVPN prefix.
We should correctly form the prefix based on the EVPN route-type.
bgpd: distinguish between frr prefixlen and packet prefixlen for EVPN type-5 routes
for EVPN routes prefixlen filed in struct prefix
represents the sizeof of the struct rather than the actual prefix len.
This is later used in looking up route node in RIB.

bgpd: set vrf originator ip to kernels local-ip
For EVPN type-5 route the NH in the NLRI is set to the local tunnel ip.
This information has to be obtained from kernel notification.
We need to pass this info from zebra to bgp in l3vni call flow.
This patch doesn't handle the tunnel-ip change.

bgpd: move rd id bitfield to bgp_master
currently, we have a rd_id bitfield
to assign an unique index for auto RD.
This bitfield currently resides under struct bgp which seems wrong.
We need to shift this to a global space
as this ID space is really global per box.
One more reason to keep it at a global data structure is,
the ID space could be used by both VNIs and VRFs.

bgpd: handle different sequence of bgp vrf create/delete
BGP VRF can be created/deleted either via config or via l3vni add/del.
We need to handle various sequences.
1. If user config is presented, an l3vni del should not delete the vrf instance
2. do not write bgp config in show running for auto created vrf
2. If l3vni present, disallow the cli for deleting bgp vrf instance
3. If l3vni is added and vrf config is present set the flags properly
4. if bgp vrf is configured unset the AUTO flag

Currently, kernel doesn't support ipv6 routes with ipv4 nexthops.
To avoid the crash,
we will only attach l3-vni related
RTs/ecommunities only to ipv4 host routes.

zebra: Reinstall remote VTEP next hop when it becomes stale
When a remote VTEP next hop entry (for symmetric routing) becomes
stale, reinstall it. This makes the behavior the same as what is
done for remote host next hops (for asymmetric routing and ARP
suppression).

bgpd: uninstall all nh/rmac when l3vni is deleted
Upon a l3vni delete (no vni under a vrf) is executed,
we should uninstall all the RMACs and NHs associated with the l3vni.
This is because by the time we get a route delete in zebra
l3vni is already deleted and we dont have refernce to RMACs and NHs
