For link-local IPv6 next hops, the next hop tracking is implemented based
on interface status changes. For this purpose, the ifindex is stored in
the NHT. Reset this value if a change in ifindex is noticed, such as for
example after a restart of the networking service.
Also add some additional debug logs.

Updates: "bgpd: Switch LL nexthop tracking to be interface based"
Ticket: RM 2575386
Testing Done:
1. Manual verification
2. Precommit (#156), evpn-smoke (#155), bgp-smoke (#157), vrl (#158)
-- Precommit is clean, reported failures in evpn-smoke & vrl are resolved
-- some other tests fail in evpn-smoke, bgp-smoke & vrl, appear to be existing
-- or unrelated failures
One of the configure-time test programs produces a warning with
gcc 9 (at least), so it fails if -Werror is enabled. Fix that.

This logs the unique ID prefix from the xref that each log message call
has, and adds on/off knobs for both EC and unique ID printing.

This parametrized use of flog with variable EC and priority doesn't mesh
particularly well with the xref code & there isn't really much reason to
not use fixed/constant calls like this.

Just small utilities for when you already have a struct fbuf (i.e. when
bprintfrr() is used to construct longer text from multiple pieces.)

Fix places where we are outputing an extra space. This was
because it was prepping for vrf but we may not have a vrf.

no point in scheduling an LSP refresh immediately if we know it is
going to be postponed again due to the network still being in its
instability grace period

when we receive an event from BFDD and we end up throwing it away,
make sure that we log (with debug guards) the reason for this, so
we can troubleshoot issues like the one addressed by the previous
commit.

A wrong check was silently skipping the initialization of the bfd_session
struct in the adjacency if the router was not configured for IPv6. This
would cause BFD events to be ignored regardless of the configuration.
Also add a function to return the "name" of an adjacency and use it in a
couple of places, including the new log, instead of repeating the same
code in a bunch of places.
