* When failing a config transaction due to a VRID conflict, describe the
error in the provided space
* When validating, allow the NB userdata lookup for interface object to
soft fail; but when applying, assert if it does not exist

The passive mode is briefly described in the RFC 5880 Bidirectional
Forwarding Detection (BFD), Section 6.1. Overview:
> A system may take either an Active role or a Passive role in session
> initialization. A system taking the Active role MUST send BFD
> Control packets for a particular session, regardless of whether it
> has received any BFD packets for that session. A system taking the
> Passive role MUST NOT begin sending BFD packets for a particular
> session until it has received a BFD packet for that session, and thus
> has learned the remote system's discriminator value. At least one
> system MUST take the Active role (possibly both). The role that a
> system takes is specific to the application of BFD, and is outside
> the scope of this specification.

We were querying the NB for an interface and expecting it to exist, but
we were doing this during a validation run when the interface hasn't yet
been created, resulting in an abort. Adjust validation checks to handle
this scenario.

Changing properties on an autoconfigured VRRP instance results in its
pointer being stored as a userdata in the NB tree, leading to UAF when
autoconfigure deletes the instance and then later NB operations take
place using the now-stale pointer.

We were noticing registration time of the last nht time.
Let's just store the original time, although I am a bit
dubious about the usefulness of this.

Don't use the same starting time for all SPF trees otherwise the
results won't be accurate (they will accumulate instead of being
computed separately).

This should simplify all code that needs to iterate over all
adjacencies of a given area (iterating over all adjacencies of all
circuits is cumbersome).
While here, repurpose isis_adj_exists() into a lookup function,
making it more generally useful.

The global isis structure can't be created/destroyed using the CLI,
so there's no need to define a QOBJ for it.

Make that function accept an IS-IS area pointer instead of an
area name, making it more in line with the rest of the code base
(*delete() functions shouldn't perform lookups internally).

Some commands were using IS-IS while others were using ISIS. Fix
this inconsistency (prefer the former option for obvious reasons).

This fixes a problem where "show isis summary" could display
inconsistent information about the IPv6 dst-src SPT when
"ipv6-dstsrc" wasn't explicitly configured.

A recent refactoring changed how isisd parses SR information from
the LSPDB and introduced a regression that prevents Prefix-SIDs to
work over unnumbered interfaces. Fix this.

With these changes the IS-IS SR topotest should run to completion
about twice as fast compared to before (4 -> 2 minutes on my
machine).

Give the FRR users some examples of gRPC usage in scripts to let them

Suppose you have more than 2 addresses on a pim interface:
lo up default 10.255.0.1/32
10.255.0.101/32
10.255.0.254/32
A `show ip pim int lo` gives us this:
eva# show ip pim interface lo
Interface : lo
State : up
Address : 10.255.0.1 (primary)
10.255.0.101/32
When we go look at the code that pulls secondary addresses in
we are using a prefix_cmp to know if we know about a secondary already
but were expecting true values instead of -1/0/1 being returned.
Modify code so that pim sees all secondary addresses

Router Information are contained in opaque LSAs and when such a LSA
is received a new SR node for the advertising router is created.
However, the RI related data is currently not set when such a SR node
already exists. This can happen when e.g. link and prefix information
arrive before the RI and therefore an SR node is created.
This is now fixed by setting the data everytime the RI is received,
independent of the SR node already existing or not.
