When we run in non-mt mode, we should consider links which have either
working IPv4 or IPv6 active and look at the neighbors nlpids to judge
wether a link is usable.
Fixes: #3336
Null check of 'rn' returned by bgp_node_lookup() because it could be
deferenced afterwards into bgp_nexthop_get_node_info()

This bakes our YANG models straight into the library/daemons, so they
don't need to be loaded from /usr/share/yang. This makes the
installation quite a bit more robust, as well as gets us halfway to
running uninstalled. (The other half is baking in the extension type
module.)
The /usr/share/yang directory is still searched as a fallback, as well
as for the experimental YANG model translator. This is likely to stay
as is for the time being.

We only support:
* --enable-shared --disable-static --disable-static-bin
* --enable-shared --enable-static --disable-static-bin
* --enable-shared --enable-static --enable-static-bin
(The second option is not particularly useful.)

* The function bgp_router_id_zebra_bump() will check for active bgp
peers before chenging the router ID.
If there are established peers, router ID is not modified
which prevents the flapping of established peer connection
* Added field in bgp structure to store the count of established peers

Enable/disable duplicate address detection
there are 3 actions
warning-only: Default action which generates
only frr warning (syslog) to user for any
duplicate detecton
freeze: Permanently freezes address, manual

The if_is_loopback() function is the right abstraction for identifying
loopback interfaces. There should be no reason for not using it in the
router-id code.

ABR summary should contain best intra prefix LSA.
There might be a case where intra-prefix route with different
cost from different advertising router present, summary
advertisement should only consider best intra-prefix route.
A route which is marked for remove, while purging the route's
ABR summary LSA also remove summary route from the summary
table.
Ticket:CM-22665
Testing Done:
Validate on ABR topology, intra-prefix route with
different cost, a higher cost intra-prefix route skip from sending
ABR summary LSA.
