bgpd: fix bgpd core when unintern attr
When the remote peer is neither EBGP nor confed, aspath is the
shadow copy of attr->aspath in bgp_packet_attribute(). Striping
AS4_PATH should not be done on the aspath directly, since
that would lead to bgpd core dump when unintern the attr.

On removal, ensure that the ifp->node is set to a null

tests: Allow ping to run multiple times before failing
the bgp_default_originate test brings up the topology and
then immediately pings. Which sometimes fails. This is
of course possible since the first ping might actually fail
due to arp going on. So let's give it a second chance or two.
Especially since the test, at this point, is just installing
a default route.

tests: ospfapi: fix non-determinism in test
fixes #13584
The test had the ospf client injecting multiple opaque LSAs on 5s pace,
but the test itself verified and advanced on an LSA in the middle of
that sequence and not the last one. Then the test reset the ospf client
and originating router. If a later injected LSA managed to get in to the
router and flooded prior to the client/router reset then the opaque data
or sequence number could differ from the expected value.

from neighbors on the interface is unconditionally (see commit c706f0e32ba8aa8780a0618b6fbba364c383ae05). In some cases, this
change wasn't desirable and this feature makes delayed reflooding
configurable for P2MP interfaces via the CLI command:

tests: Slow bgp_default_originate test down slightly
The test is performing these steps:
a) get timestamp of route installed in zebra
b) <make changes>
c) get new timestamp of route installed in zebra
If < 1 second happens between A and C the test
assumes that something went wrong, as that it is
testing to see if the route was reinstalled <yes I know>.
Just sleep 1 second after a) happens so that if a reinstall
happens we can easily see it, and we also know that if a
reinstall doesn't happen then the new timestamp will
always be 1 second or greater.
