A MAC entry cannot be deleted while a neigh is referencing it. It seems
there is some race condition where this may be happening. The log is
to help identify those cases.

It is now 4bits of type and 28bits of value -
1. type=0 is for L3 NHG
2. type=1 is for L2 NH
3. type=2 is for L2 NHG

This is an optimization to reduce the number of L2 nexthops. A
l2 or fdb nexthop simply provides the dataplane with a nexthop ip-
torm-12:mgmt:~# ip nexthop
id 268435461 via 27.0.0.20 scope link fdb
id 268435463 via 27.0.0.20 scope link fdb
id 268435465 via 27.0.0.20 scope link fdb
So there is no need to allocate a nexthop per-ES/per-VTEP. There
can be 100+ ESs per-VTEP so this change cuts the scale down by a
factor of 100.

When a local ES flaps there are two modes in which the local
MACs are failed over -
1. Fast failover - A backup NHG (ES-peer group) is programmed in the
dataplane per-access port. When a local ES flaps the MAC entries
are left unaltered i.e. pointing to the down access port. And the
dataplane redirects traffic destined to the oper-down access port
via the backup NHG.
2. Slow failover - This mode needs to be turned on to allow dataplanes
not capable of re-directing traffic. In this mode local MAC entries
on a down local ES are re-programmed to point to the ES-peers'
NHG. And vice-versa i.e. when the ES comes up the MAC entries
are re-programmed with the access port as dest.
Fast failover is on by default. Slow failover can be enabled via the
following config -
evpn mh redirect-off

As a part of extended MM handing a MAC can be updated from local
to remote while being referenced by SYNC neighs (this is really a
temporary/small window). During this window if the MAC transitions
back to local again we need to re-inforce the previous SYNC flags
(based on the sync-neigh count) as subsequent SYNC updates to the
MAC will be de-duped and ignored.

When a local mac is deleted by the dataplane zebra can re-install it
if the MAC is a SYNC MAC (learned from ES peers). The "local_inactive"
bit must be set as a part of the re-install to prevent zebra turning
around and advertising the MAC as locally active.
Also fixed up some debug logs in the slow-fail path to include the VNI.

NHG is activated i.e. programmed in the dataplane only if there
are active-VTEPs associated with it. When a NHG is de-activated
all the remote-mac entries associated with it need to be removed
before the NHG is removed.

The lookup for non default VRFs was always using a tableId; if not
provided, we were defaulting to RT_TABLE_MAIN. This is fine for the
default VRF but not for others. As a result, the command was silently
failing for non-default VRFs unless we also specified the correct tableId.
Fix this by only performing the lookup using the tableId if it is
provided; else use zebra_vrf_table.

A couple NHG messages we were logging as errors are a bit spammy
in usecases where you routinely add/remove interfaces (VM heavy
deployments). Its not really an error a user cares about and
more for a developer to know what went wrong after the fact so
it makes more sense for these to be under a debug rather than
an error since seeing them does not implicitly mean error during
those usecases.

There are two fixes in this commit -
1. Prevent implicit deletion of (*,G) entries during (S,G) cleanup.
This is done by creating a dummy reference on all (*,G) entries.
This is needed for a hash-walk based table cleanup.
2. Free up the SG hash table when the VRF is deleted.

Earlier type-3 ESI was the only format supported for evpn-mh. Updated the
CLI to allow a 10-byte type-0 ESI.
Both type-0 and type-3 ESIs are statically configured; just in two different
ways -
1. type-0 is configured as a complete 10-byte string
2. type-3 is configured as a 6-byte es-sys-mac and a 3-byte
local-discriminator.
Sample config -
!
interface hostbond1
evpn mh es-id 00:44:38:39:ff:ff:01:00:00:01
!
This is a CLI-only change and has no functional impact.

Commit: 1d376ff539 removed
the code to find nexthops for the POINTOMULTIPOINT and
replaced it with a generic bit of code that was
supposed to handle both POINTOPOINT and POINTOMULTIPOINT
the problem is that the ospf rfc states that the
network mask on point to multipoint should be /32
which will not allow you to properly do a prefix match
on it against the network.
Restore original behavior as much as possible and leave
the new POINTOPOINT code alone.
