When isis_sock_init fails in isis_circuit_up, isis_circuit_down would
be called to cancel timers which were scheduled. However
isis_circuit_down would immediately return, since the state had not been
changed to 'UP' yet.
Fix this by having isis_circuit_down always cancel all the timers.

This test case happens in scenarios with mininet, where external netns
may be impossible for the local instance to be modified. The error is
ignored and the netns parsed is ignored too.

EVPN ND ext community support NA flag R-bit, to have proxy ND.
Set R-bit in EVPN NA if a given router is default gateway or there is a
local
router attached, which can be determine based on local neighbor entry.
Implement BGP ext community attribute to generate and parse R-bit and
pass along zebra to program neigh entry in kernel.
Upon receiving MAC/IP update with community type 0x06 and sub_type 0x08,
pass the R-bit to zebra to program neigh entry.
Set NTF_ROUTER in neigh entry and inform kernel to do proxy NA for EVPN.

It has not been properly documented yet how to enable the RPKI module with BGP when having installed FRR with RPKI support. This PR seeks to add a section to the user documentation about this. So users will not have to resolve to searching the internet and looking through the FROG mailing list threads for answers.
It was reported that "show ipv6 route vrf <vrfname>", "show ipv6 route
vrf <vrfname> ::/0 " or "show ipv6 route vrf <vrfname> json" all
displayed that the nexthop was in the default vrf. This was because
the kernel netlink messages would supply the RTA_OIF of the loopback
interface for the kernel-created default route for the vrf, where ipv4
did not supply any RTA_OIF. This fix suppresses the display if the
nexthop and route entry are in different vrfs and the nexthop is
NEXTHOP_TYPE_BLACKHOLE.

Kernel requests via netlink are synchronous.
Therefore we do not need to specify a need for a ACK and
we can make the netlink_cmd NONBLOCKING
1) If the netlink message is going to cause an error
we will still get one. Since results from the kernel
are synchronous we will get the error message on the
netlink_cmd socket and handle it
2) If the netlink message is going to send more than
one packet we will still get them all. Since the results
from the kernel are synchronous we will receive all data.

The search algorithm for interface based on ifindex only is adapted to

interface index.

the interface lookup based on ifindex in the case the target vrf is
unknown is using the generic vrf api. Like that, in the case of vrf
based netns, the search across different netns other than the default
one are not searched.

The interface lookup algorithm is different according to if we are on
netns vrf or not. If we are on the former case, then we only have to
parse the interfaces of the netns, while if we are on the other case, we
have to parse all the interfaces of all the vrfs ( since index is not
overlapping in the latter case).
