bgpd: always display keepalive/hold intervals
`show bgp neighbors <peer> [json]` was only displaying the configured
keepalive and holdtime intervals when they differed from the default
values. Since default config is still config, let's make sure these
values are always displayed.
However it mistakenly changed the logic to only display the peer's
timers if the configured value was non-zero. This updates the logic to
check PEER_FLAG_TIMER to determine if the values were configured,
given 0 is a valid value (to disable keepalives).
pimd: Querier to non-querier transition to be ignored
Fixing IGMPv2 ANVL Conformance issue 3.10
As per RFC 2236 section 3, when the leave message is received at a querier,
it starts sending Query messages for "last Member Query Interval*query count"
During this time there should not be any querier to non-querier
transition and the same router needs to send the remaning queries.
Currently the code is handling this scenario only when leave is receive
for a group and the query is received for the same group.
But we need to handle it irrespective of group since the querier
election is based on interface and not group.

A SR policy matches a BGP nexthop based on the IP address of
the nexthop and the color of the route (color may be assigned

The order of events (BGP route arrival, route-map definition,
policy and candidate-path definition) should not affect the

These changes add tests for:
- removing/adding BGP route after policy and routemap are
defined and held constant
- changing route map color to be different from policy color,
and then changing back to match
after each change, the policy should be observed to be in effect
unchanged from before, i.e., the route's nexthops should reflect
the matching SR policy.

then if an interface went down all kernel and system routes would
be re-evaluated. There exists situations where a kernel route can
exist but the interface itself is not exactly in a state that is
ready to create a connected route yet. As such when any interface
goes down in the system all kernel/system routes would be re-evaluated
and then since that interfaces connected route is not in the table yet
the route is matching against a default route( or not at all ) and
is being dropped.
Modify the code such that kernel or system routes just look for interface
being in a good state (up or operative) and accept it.

lib, zebra: Notice when a nexthop is set linkdown
When a nexthop is set RTNH_F_LINKDOWN, start noticing
that this flag is set. Allow FRR to know about this
flag but at this point do not do anything with it.

lib: Increase nexthop flags size to 16 bits
commit: 5609e70fb87a3b23b55629a33e5afb298974c142
Added a new flag to the `struct nexthop` and
this addition of a flag caused the flags size to
be too small. Increase the size of flags to
allow more flags to be had.

zebra: Fix bug in netconf handling where dplane would drop the change
When reading a on the fly change of an interested netconf netlink
message. The ifindex and ns_id for the context was being set for the sub structure
but not for the main context data structure and zebra_if_dplane_result
was dropping the result on the floor because it was expecting the ns_id and
the interface id to be in a different spot.
