Move `is_default_prefix` variations to `lib/prefix.h` and make the code
use the library version instead of implementing it again.
NOTE
----
The function was split into per family versions to cover all types.
Using `union prefixconstptr` is not possible due to static analyzer
warnings which cause CI to fail.
The specific cases that would cause this failure were:
- Caller used `struct prefix_ipv4` and called the generic function.
- `is_default_prefix` with signature using `const struct prefix *` or
`union prefixconstptr`.
The compiler would complain about reading bytes outside of the memory
bounds even though it did not take into account the `prefix->family`
part.

ospf6_router_id_update function is used by ospf6_router_id_update_zebra

This patches makes the functions to (un)configure ospf6 router-id use
the same function as ospf6_router_id_update_zebra.

The code had no limits on addresses configured on an interface running
ospf6d. The code would crash when more than 100 addresses were added.
This change limits the number of interface address to 100 if mtu is set
to the default value. If the mtu is set to a jumbo packet size or larger
we will support 200 interface addresses.

Back when I put this together in 2015, ISO C11 was still reasonably new
and we couldn't require it just yet. Without ISO C11, there is no
"good" way (only bad hacks) to require a semicolon after a macro that
ends with a function definition. And if you added one anyway, you'd get
"spurious semicolon" warnings on some compilers...
With C11, `_Static_assert()` at the end of a macro will make it so that
the semicolon is properly required, consumed, and not warned about.
Consistently requiring semicolons after "file-level" macros matches
Linux kernel coding style and helps some editors against mis-syntax'ing
these macros.

The rib process of handling routes has been unified a bit more
and as a result v6 LL routes are now showing up as a result
of a `redistribute connected`. Doing anything with these
routes is a policy decision that should be enforced by the
individual routing daemons not by zebra. As such add a bit
of code to isisd, ripngd and opsf6d to handle them. The bgp daemon
already handles this situation.
Signed-off-by: Donald Sharp <sharpd@cumulusnetworks.com>
Some daemons like ospfd and isisd have the ability to advertise a
default route to their peers only if one exists in the RIB. This
is what the "default-information originate" commands do when used
without the "always" parameter.
For that to work, these daemons use the ZEBRA_REDISTRIBUTE_DEFAULT_ADD
message to request default route information to zebra. The problem
is that this message didn't have an AFI parameter, so a default route
from any address-family would satisfy the requests from both daemons
(e.g. ::/0 would trigger ospfd to advertise a default route to its
peers, and 0.0.0.0/0 would trigger isisd to advertise a default route
to its IPv6 peers).
Fix this by adding an AFI parameter to the
ZEBRA_REDISTRIBUTE_DEFAULT_{ADD,DELETE} messages and making the
corresponding code changes.

Store zebra router-id in global structure.
Before router ospf6 instance created,
zebra router-id callback called.
During ospf6 main execution zebra init happens,
but default instance does not execute until
cli replay 'router ospf6'.
Call ospf6_router_id_change during 'router ospf6'
to assign zebra router id to ospf6 instance.
Ticket:CM-19937
Testing Done:
Assign Loopback /32 (6.6.6.6/32) address,
restart frr with (router ospf6 in frr.conf).
ospf6 default instance assigned 6.6.6.6 router-id.

Performance tests showed that, when running on a system with a large
number of interfaces, some daemons would spend a considerable amount
of time in the if_lookup_by_index() function. Introduce a new rb-tree
to solve this problem.
With this change, we need to use the if_set_index() function whenever
we want to change the ifindex of an interface. This is necessary to
ensure that the 'ifaces_by_index' rb-tree is updated accordingly. The
return value of all insert/remove operations in the interface rb-trees
is checked to ensure that an error is logged if a corruption is
detected.

This is a fallout from PR #1022 (zapi consolidation). In the early days,
the client daemons would allocate enough memory to send all nexthops
to zebra. Then zebra would add all nexthops to the RIB and respect
MULTIPATH_NUM only when installing the routes in the kernel. Now things
are different and the client daemons can send at most MULTIPATH_NUM
nexthops to zebra, and failure to respect that will result in a buffer
overflow. The MULTIPATH_NUM limit in the new zebra API is a small price
we pay to avoid allocating memory for each route sent to zebra.
