Use the `--enable-address-sanitizer` option instead of the manual
version using environment flags.
This also avoids the problem of having to remember to skip clippy with
the custom flags:
```
make -C lib CFLAGS="-g -O2" LDFLAGS="-g" clippy
```
The snippet above is not needed with `--enable-address-sanitizer`!

We should test for `-fsanitize=memory` instead of `-fsanitize=thread`
when enabling memory sanitizer. While here, fix the error message.

There are several places in the pim where we are mixing up
zlog_warn w/ zlog_debug and vice versa. If we are protecting
a zlog_warn w/ a debug is it really a warn? If we have an actual
error situation we should also warn about it.

Don't bother tracking ipv6 link locals to determine if a map
should be installed. Every interface has a route of `fe80::/64`
so its just going to return the arbitrarily first one it finds
when it resolves it and hands it back to us.
Instead, just track the interface we specify along with it.

inet_pton() is used to parse ipv4 addresses internally, therefore FRR
does not support octal notation for quads. The ipv4 cli token validator
should make sure that str2prefix() can parse tokens it allows, and
str2prefix uses inet_pton, so we have to disallow leading zeros in ipv4
quads.
In short, 1.1.1.01 is no longer valid and must be expressed as 1.1.1.1.

Provide a few bread crumbs to the operator that it might not be as
useful as they would hope.

commit ee8a72f315
broke the usage of ZEBRA_ROUTE_ALL as a valid redistribution
command. This commit puts it back in. LDP uses ZEBRA_ROUTE_ALL
as an option to say it is interested in all REDISTRIBUTION events.

Start the work in sharpd to allow the testing of redistribution
of routes. Namely telling zebra to tell us about redistribution events
via the callback.
Future work here will allow sharpd to specify the redistribution
events it wants and to allow us to track that via counters.

The vrf_id in `zsend_interface_vrf_update()` is encoded as
a long via `stream_putl()`, we should decode it as such
as well.

In a leaf/spine topology with only IBGP connections, where
the same network is being redistributed at multiple points
in the network ( say a redistribute connected at both leaf and spines )
we end up in a state where zebra gets very confused.

Effectively we have ibgp routes recursing through ibgp routes
and there is no metric to discern whom to listen to.
This draft:
https://tools.ietf.org/html/draft-ietf-idr-bgp-optimal-route-reflection-19
appears to address this issue. From looking at both cisco and arista
deployments they are handling this issue by having the route reflector
prefer the localy learned routes over from their clients.
Add this topology, in a broken state, so that when we do fix this issue
it is a simple matter of touching this topology up and re-adding it
to the normal daily builds. I also wanted to add this topology
since it is in a state of `doneness` and I wanted to move onto
my normal day job without having to remember about this test.
This topology is not configured to be run as part of the normal
topotests.

RFC 5303 states:
If the system ID and Extended Local Circuit ID of the neighboring
system are known (in adjacency three-way state Initializing or
Up), the neighbor's system ID SHALL be reported in the Neighbor
System ID field, and the neighbor's Extended Local Circuit ID
SHALL be reported in the Neighbor Extended Local Circuit ID field.
There is nothing written about only setting the Extended circuit ID of the
adjacency only when we bring the three-way adjacency up.
In fact, we should always update it, to avoid the problem described in #4783.

a failure is detected we can't rely on the setup anymore, since most of
the tests assume the previous worked.
