zebra: add interface address apis for dplane
Add new apis for dplane interface address handling, based on
the existing api. The existing api is basically split in two:
the first part processes an incoming netlink message in the
dplane pthread, creating a dplane context with info about
the event. The second part runs in the main pthread and uses
the context data to update an interface or connected object.
zebra: Fix IPv4 routes with IPv6 link local next hops install in FPM
Description: Currently IPv4 routes with IPv6 link local next hops are
not properly installed in FPM.
Reason is the netlink decoding truncates the ipv6 LL address to 4 byte
ipv4 address.
Ex : fe80:: is directly converted to ipv4 and it results in 254.128.0.0
as next hop for below routes
show ip route
Codes: K - kernel route, C - connected, S - static, R - RIP,
O - OSPF, I - IS-IS, B - BGP, E - EIGRP, N - NHRP,
T - Table, v - VNC, V - VNC-Direct, A - Babel, D - SHARP,
F - PBR, f - OpenFabric,
> - selected route, * - FIB route, q - queued, r - rejected, b - backup
B>* 2.1.0.0/16 [200/0] via fe80::268a:7ff:fed0:d40, Ethernet0, weight 1,
02:22:26
B>* 5.1.0.0/16 [200/0] via fe80::268a:7ff:fed0:d40, Ethernet0, weight 1,
02:22:26
B>* 10.1.0.2/32 [200/0] via fe80::268a:7ff:fed0:d40, Ethernet0, weight
1, 02:22:26
Hence this fix converts the ipv6-LL address to ipv4-LL (169.254.0.1)
address before sending it to FPM. This is inline with how these types of
routes are currently programmed into kernel.

mroute and verifying mroutes separately. Execution time is reduced from almots 10 mins

bgpd: move rpki source after the server config
Currently the source IP parameter must be entered between destination IP
and destination port parameters. This is not obviously understandable
when you read such config so let's move the source parameter to the end
of the command line, after the whole list of destination parameters. We
can do this without any deprecation cycle as the parameter was introduced
just recently and isn't in any public release yet.

bgpd: fix default-originate route-map processing
When processing a route-map for default-originate, we actually want to
match by attributes in routes from the RIB, but set attributes in the
newly originated route. Currently, it's not the case. Instead, we
construct a dummy path combining attributes from both routes, and we end
up with multiple problems:
- match by as-path doesn't work
- communities from the matched RIB route are copied to the newly
originated route
- we corrupt the RIB routes
To fix the issue, we should use the new route-map API that allows using
separate match/set objects.

tests: Set mask to a default value for addKernelRoute
When looking for a implied host route it is not necessary
to add the `/32` to an ip route add. As such masks
will not be set in this case. Set the value of masks
to a known good value so that when the route installation
fails the test for it actually being there will tell you
that the route is not there -vs- complaining about mask
being uninited.

zebra: Send path del to bgp for local-inactive path
Problem:
When IP1:M1 (local) moved to IP1:M2 (remote-VTEP) bgpd continues to
advertise IP1:M1.
Fix:
Local path del is sent to bgp if the neigh was {local-active||peer-active}.
So path del needs to be called before the sync flags (including peer-active)
are cleared.

Description:
Change is intended for fixing the following issues related to vrf route leaking:
Routes with special nexthops i.e. blackhole/sink routes when imported,
are not programmed into the FIB and corresponding nexthop is set as 'inactive',
nexthop interface as 'unknown'.
While importing/leaking routes between VRFs, in case of special nexthop(ipv4/ipv6)
once bgp announces route(s) to zebra, nexthop type is incorrectly set as
NEXTHOP_TYPE_IPV6_IFINDEX/NEXTHOP_TYPE_IFINDEX
i.e. directly connected even though we are not able to resolve through an interface.
This leads to nexthop_active_check marking nexthop !NEXTHOP_FLAG_ACTIVE.
Unable to find the active nexthop(s), route is not programmed into the FIB.
Whenever BGP leaks routes, set the correct nexthop type, so that route gets resolved
and correctly programmed into the FIB, in the imported vrf.
Create a pid file for the router created by topotest.
By executing nsenter directly against this pid, developers
can execute commands directly from outside the unet shell.
This allows the developer to use script, tab completion, etc.,
and improves efficiency.
