nhrp, lib, zebra: add/del neighbor entry possible from nhrp
a zebra api is extended to offer ability to add or remove neighbor
entry from daemon. Also this extension makes possible to add neigh
entry, not only between IPs and macs, but also between IPs and NBMA IPs.
This API supports configuring ipv6/ipv4 entries with ipv4/ipv6 lladdr.

nhrpd: link layer registration to notifications
neighbor notifications are done in zebra. so, instead of relying on
nhrp, rely on zebra by using zebra api interface.
Consequently, the code originally used in nhrp for netlink neighor

zebra: link layer config and notification, implementation in zebra
zebra implements zebra api for configuring link layer information. that
can be an arp entry (for ipv4) or ipv6 neighbor discovery entry. This
can also be an ipv4/ipv6 entry associated to an underlay ipv4 address,
as it is used in gre point to multipoint interfaces.
this api will also be used as monitoring. an hash list is instantiated
into zebra (this is the vrf bitmap). each client interested in those entries
in a specific vrf, will listen for following messages: entries added, removed,
or who-has messages.

This patch implements new zapi api to get neighbor information that zebra knows
and that other daemons may need to know. Actually, nhrp daemons is

nhrpd: lookup appropriate ipsec path
lookup appropriate ipsec path. there are systems where the path where
the charon.vici file is not in standard paths. For that, 'ipsec
--piddir' may help in solving the path.
result of ipsec --piddir is as follow for example:
'
/etc/ike/ipsec.d/run
'
Note that the assumption is done that even if there are several
instances of strongswan across the vrfs, the charon.vici path file is
the same across vrfs. Consequently, as there is a thread per vrf that
performs vici initialisation, and file path retrieval is part of the
vici initialisation procedure, in order to avoid intempestive system
calls, use a boolean 'vici_charon_filepath_done' to avoid doing
unnecessary calls.

Current behavior has an EVPN_ENABLED check for both standard and 'no'
forms of 'advertise-svi-ip' and 'advertise-default-gw'. This prevents a
user from removing either command from running config if
'advertise-all-vni' is not present.
This commit removes/adjusts the EVPN_ENABLED checks to always allow the
'no' command so config doesn't get stuck.

BGP session not established for ipv6 link local address with vrf config
Problem Description/Summary :
BGP session not established for ipv6 link local address with vrf configyy
1.Configure ipv6 link-local address fe80::1234/64 on dut1 and fe80::4567/64 on dut2
2.Configure BGP neighbors for ipv6 link-local on both dut1 and dut2
3.Verify BGP session is UP over link-local ipv6 address

Expected Behavior :
BGP session should be established for ipv6 link local address with vrf config

tools: frr-reload fixes for deleting vrf static routes
Problems reported that in certain cases, frr-reload.py would
delete vrf static routes inadvertantly due to two different
reasons. First, vrf statics with null0 or Null0 nexthops would
fail the match since rendered as blackholes. This was already
fixed for non-vrf statics so added for vrf-based. Second,
frr-reload would fail to match due to different formats for
adding the command. If entered in the old way
"ip route x.x.x.x/x y.y.y.y vrf NAME" and rendered
in the new sway "vrf NAME\nip route x.x.x.x/x y.y.y.y" it would
fail to match do an inadvertant delete.
