Replace custom implementation or call to ipaddr_isset with a call to
ipaddr_is_zero.
ipaddr_isset is not fully correct, because it's fine to have some
non-zero bytes at the end of the struct in case of IPv4 and the function
doesn't allow that.

Update ospfd and ospf6d to send opaque route attributes to
zebra. Those attributes are stored in the RIB and can be viewed
using the "show ip[v6] route" commands (other than that, they are
completely ignored by zebra).
Example:
```
debian# show ip route 192.168.1.0/24
Routing entry for 192.168.1.0/24
Known via "ospf", distance 110, metric 20, best
Last update 01:57:08 ago
* 10.0.1.2, via eth-rt2, weight 1
OSPF path type : External-2
OSPF tag : 0
debian#
debian# show ip route 192.168.1.0/24 json
{
"192.168.1.0\/24":[

Currently `bfd_get_peer_info` should return invalid sp->family
and dp->family during fail cases.
Before this fix, in those fail cases `bfd_get_peer_info` maybe
return valid sp->family and dp->family.
This fix ensures all fail cases return invalid sp->family and
dp->family for outside callers.

Currently, it is possible to rename the default VRF either by passing
`-o` option to zebra or by creating a file in `/var/run/netns` and
binding it to `/proc/self/ns/net`.
In both cases, only zebra knows about the rename and other daemons learn
about it only after they connect to zebra. This is a problem, because
daemons may read their config before they connect to zebra. To handle
this rename after the config is read, we have some special code in every
single daemon, which is not very bad but not desirable in my opinion.
But things are getting worse when we need to handle this in northbound
layer as we have to manually rewrite the config nodes. This approach is
already hacky, but still works as every daemon handles its own NB
structures. But it is completely incompatible with the central
management daemon architecture we are aiming for, as mgmtd doesn't even
have a connection with zebra to learn from it. And it shouldn't have it,
because operational state changes should never affect configuration.
To solve the problem and simplify the code, I propose to expand the `-o`
option to all daemons. By using the startup option, we let daemons know
about the rename before they read their configs so we don't need any
special code to deal with it. There's an easy way to pass the option to
all daemons by using `frr_global_options` variable.
Unfortunately, the second way of renaming by creating a file in
`/var/run/netns` is incompatible with the new mgmtd architecture.
Theoretically, we could force daemons to read their configs only after
they connect to zebra, but it means adding even more code to handle a
very specific use-case. And anyway this won't work for mgmtd as it
doesn't have a connection with zebra. So I had to remove this option.

In order to add Link State Traffic Engineering to IS-IS, Link State library
should have been updated:
- Correct Node and Edge RB Tree comparison functions to support key > 32 bits
- Change Subnet RB Tree comparison function to take into account host part of
the prefix i.e. 10.0.0.1/24 and 10.0.0.2/24 are considered as different
- Add new function to convert IS-IS ISO system ID into Vertex or Edge key that
take into account Endianness architecture
- Correct Vertex and Edge creation and search function accordingly
- Add extra Adjacency entries in Link State Attributes for IPv6 Segment Routing
- Update send/received and show TED functions accordingly

Duplicate a couple of definitions in order to remove the bgpd
includes from this libfrr header. This is necessary to fix some
name collisions like PREFIX_LIST_IN being defined differently on
multiple daemons (as soon as other daemons start including
route_opaque.h).
Including daemon headers on libfrr headers is a bad practice and
should be avoided whenever possible.
