Current failed reasons for bgp when you have a peer that
is not online yet is `Waiting for NHT`, even if NHT has
succeeded. Add some code to differentiate this.

eva# show bgp nexthop
Current BGP nexthop cache:
192.168.44.1 invalid, peer 192.168.44.1
Must be Connected
Last update: Mon Feb 10 19:05:19 2020
192.168.201.139 valid [IGP metric 0], #paths 0, peer 192.168.201.139
So 192.168.201.139 is a peer for a connected route that has not been
created on .139, while 44.1 nexthop tracking has not succeeded yet.

RCA:
When we install IPv6 prefix imported from EVPN RT-5 in vrf, nexthop of the IPv6
route should be IPv4 mapped IPv6 address. In function
install_evpn_route_entry_in_vrf, we generate a new attribute with IPv4 mapped
IPv6 nexthop, but we use parent->attr while creating the actual route.
Thus, Ipv4 nexthop is assigned to this route.
Because of this incorrect nexthop, we observed a crash in function
update_ipv6nh_for_route_install.
Fix:
Pass the new attribute with Ipv4 mapped Ipv6 nexthop to
bgp_create_evpn_bgp_path_info

Multi instance ospf support was broken due to PR #4564.
Adding fix back and extra checks to support multi instance
OSPF.

Copy the fix made in 'lib/if.c' to 'lib/routemap_northbound.c' so we can
have a working YANG model when compiled with GCC version less than 5.

Keep a list of hook contexts used by northbound so we don't lose the
pointer when free()ing the route map index entry data.

Allow old CLI users to still print their configuration without migrating
to northbound.

Two fixes here:
* Don't attempt to use `vty` pointer in vty;
* When `vty` is unavailable output to log;

This fixes a warning on daemons that use route map about filter yang
model not being included in the binary.

Based on the route map old CLI, implement the route map handling using
the exported functions.
Use a curry-like programming pattern avoid code repetition when
destroying match/set entries. This is needed by other daemons that
implement custom route map functions and need to pass to lib their
specific destroy functions.

Important changes:
* Rename top container `route-map` to `lib`;
* Rename list `instance` to `route-map`;
* Move route map repeated data to list `entry`;
* Use interface reference instead of typedef'ed string;
* Remove some zebra specific route map conditions;
* Protect `tag` set value with `when "./action = 'tag'"`;

Indicate in the doc clearly that we do not support the dynamic
creation of pbr maps for sub-interfaces when the master has
an interface. Such as in vlans. It must be explicitly added.

bgp flowspec packets are being forged correctly. There is no need to
check for bgp length, as the bgp nlri length is checked at reception.
