Issue #9983 explains what is wrong with the GR helper mode.
To unblock the CI that fails almost all the time on the ospf_gr_topo1
test, remove the commands and disable the test. Also add a reminder to
completely remove the helper mode if no one fixes the code in a month.

It's strictly optional, but… the backtraces are really much better.
Specifically, `libunwind` is notably more capable in figuring out
function names compared to glibc/libexecinfo `backtrace_symbols()`.

show/clear DEFUNs always require either peer label or IP address to be
specified, so if `label` is NULL then `peer_str` is definitely not NULL.
But Coverity doesn't know about that, so it complains about possible
NULL dereference of `peer_str`. This commit should make Coverity happy.

Might be possible to do this more cleanly some way, but that way is not
obvious, so here's the "simple & dumb" approach.

Looks much prettier if `libunwind` is available, but works with glibc or

Problem:
L2-VNI SVI down followed by L2-VNI's vxlan device
deletion leads to stale entry into L3VNI's
L2-VNI list.
Solution:
When L2-VNI associated SVI is down, default vrf
is the new tenant vrf.
Remove L2-VNI from L3VNI's l2vni list as
L3VNI/VRF is no longer valid in absence of associated
SVI.
When SVI is up re-add L2-VNI into associated VRF's
L3VNI.
The above remove/add from the L3VNI's L2VNI list is
already done when vxlan or L2-VNI is flaped, just need
to handle when SVI is flapped.
Ticket:#2817127
Reviewed By:
Testing Done:
After deleting SVI following by L2-VNI deletion,
L3VNI's L2-VNI list delets the L2-VNI. (no stale entry).
After adding back SVI/L2-VNI, L3VNI list adds back the
L2-VNI and it is associated right tenant VRF.

common_cli.c disables logging by default so stdio is usable as vty

most tests, but not all; sometimes we do want log messages.

The `struct thread **ref` that the thread code takes is written to and
needs to stay valid over the lifetime of a thread. This does not hold
up if thread pointers are directly put in a `vector` since adding items
to a `vector` may reallocate the entire array. The thread code would
then write to a now-invalid `ref`, potentially corrupting entirely
unrelated data.
This should be extremely rare to trigger in practice since we only use
one c-ares channel, which will likely only ever use one fd, so the
vector is never resized. That said, c-ares using only one fd is just
plain fragile luck.
Either way, fix this by creating a resolver_fd tracking struct, and
clean up the code while we're at it.

The crash is in the on->ospf6_if pointer is NULL. The only way this could
happen from what I can tell is that the event is added to the system
and then we immediately delete the interface, removing the memory
but not freeing up the adj_ok thread event.
