This test ensures that MPLS VPN routes can be installed into a
gre interface with route-map l3vpn next-hop encapsulation command
set. On the other hand, if this command is not set, incoming bgp
routes are not considered as valid.

When a route imported from l3vpn is analysed, the nexthop from default
VRF is looked up against a valid MPLS path. Generally, this is done on
backbones with a MPLS signalisation transport layer like LDP. Generally,
the BGP connection is multiple hops away. That scenario is already
working.
There is case where it is possible to run L3VPN over GRE interfaces, and
where there is no LSP path over that GRE interface: GRE is just here to
tunnel MPLS traffic. On that case, the nexthop given in the path does not
have MPLS path, but should be authorized to convey MPLS traffic provided
that the user permits it via a configuration command.
That commit introduces a new command that can be activated in route-map:
> set l3vpn next-hop encapsulation gre
That command authorizes the nexthop tracking engine to accept paths that
o have a GRE interface as output, independently of the presence of an LSP
path or not.
A configuration example is given below. When bgp incoming vpnv4 updates
are received, the nexthop of NLRI is 192.168.0.2. Based on nexthop
tracking service from zebra, BGP knows that the output interface to reach
192.168.0.2 is r1-gre0. Because that interface is not MPLS based, but is
a GRE tunnel, then the update will be using that nexthop to be installed.

Description:
ospf process is crashing when the current router acts
as GR helper and it received a new lsa.
Here, ospf_lsa_different() is being called without checking
'old' pointer. It is asserted in ospf_lsa_different() api
if the 'old' pointer is NULL.
corrected this by validaing old pointer before calling
ospf_lsa_different() api.
