do not add a new route type, and consider 0 as a value meaning
that zebra should be the owner.

zapi_nbr structure is renamed to zapi_neigh_ip.
Initially used to set a neighbor ip entry for gre interfaces, this
structure is used to get events from the zebra layer to nhrp layer.
The ndm state has been added, as it is needed on both sides.
The zebra dplane layer is slightly modified.
Also, to clarify what ZEBRA_NEIGH_ADD/DEL means, a rename is done:
it is called now ZEBRA_NEIGH_IP_ADD/DEL, and it signified that this
zapi interface permits to set link operations by associating ip
addresses to link addresses.

Currently, if NSSA area is configured before redistribution is enabled,
Type-7 LSA's are installed and flooded. But if NSSA area is configured
after redistribution is enabled, Type-7 LSA's are not installed.
With this change, when NSSA area is configured, schedule a task that
scans for external LSA's. If they exist, install Type-7 and flood to
all NSSA Areas.
There already was an attempt to fix this problem in 0f321812f where
ospf_asbr_nssa_redist_task() was triggered in ospf_abr_task_timer().
This turns out to be incorrect place for this operation because it's
a one-off operation needed only after "area <ID> nssa" execution. And
ospf_abr_task_timer() is a periodic operation. Triggering
ospf_asbr_nssa_redist_task() in ospf_abr_task_timer() caused a problem
that was fixed in 945eec2b6 making the problem with NSSA area
configured after redistribution actual again.

The idea of the "with-defaults" flag is to show the default values for
parameters that were not configured by the user. But bfdd incorrectly
shows the default values for all parameters, including the
user-configured ones.

The first change in this commit is the processing of the VRF termination.
When we terminate the VRF, we should not delete the underlying interfaces,
because there may be pointers to them in the northbound configuration. We
should move them to the default VRF instead.
Because of the first change, the VRF interface itself is also not deleted
when deleting the VRF. It should be handled in netlink_link_change. This
is done by the second change.

This is useful to go back in the past and check when was that prefix appeared,

endian.h supplies be*toh() and htobe*() functions. This fixes the build
on musl libc. On other systems it seems endian.h comes in transitively
from some other header.
(Also, all .c files should have config.h or zebra.h as the first
include, even if it works without that it's b0rked and only works due to
luck.)

Currently we have a "route-map optimization" command which is entered
from inside the route-map entry but actually applies to the whole
route-map. In addition, this command is not shown in the running-config
and not stored to the startup-config during "write".
Let's add a new command on the config node level to control this setting
and show it in the running-config to make possible to save it during
"write".
The old command is saved for the backward compatibility but hidden and
marked as deprecated.

Can't have things duplicate in libpath.a and pathd directly, they'll
crash into eath other on linking. No idea why this doesn't error out in
our CI builds, but it definitely breaks LTO builds.

Most software doesn't overwrite its own config files; vtysh's 'wr mem'
may be confusing, so add a note to the config file explaining changes
made may be overwritten.

Most of these are many, many years out of date. All of them vary
randomly in quality. They show up by default in packages where they
aren't really useful now that we use integrated config. Remove them.
The useful ones have been moved to the docs.
