When an EVPN prefix flaps too quickly such that the new advertisement
is received prior to the full processing of the prior withdraw, we may
get into a state where the route doesn't get imported properly into
MAC or IP VRFs. Ensure that we do the route import in such cases.

1. This check is absolutely useless. Nothing keeps user from deleting
the address right after this check.
2. This check prevents zebra from correctly reading the user config with
"set src" because of a race with interface startup (see #4249).
3. NO OPERATIONAL DATA USAGE ON VALIDATION STAGE.
Fixes#7319.

If we don't advertise any capabilities (dont-capability-negotiate), we
shouldn't set msg size to 65k only if received this capability from another
peer.
Before:
```
~/frr# vtysh -c 'show ip bgp update-group' | grep 'Max packet size'
Max packet size: 65535
```
After:
```
~/frr# vtysh -c 'show ip bgp update-group' | grep 'Max packet size'
Max packet size: 4096
```

Until now, when bgp flowspec entry action was to redirect to a vrf, a
default route was installed in a specific table. that route was a vrf
route leak one. The process can be simplified, as vrf-lite already
has a table identifier. Actually, because policy routing is used to
redirect traffic to a defined table (with ip rule command), use
the table identifier of the VRF.

- A more general fix for the bgp listener test which requires interfaces be
configured in the kernel when the bgpd daemons are launched.

Tested with full feed, this stucks and bgpd even stops responding.

This command is currently always treated as an "unset" command, assuming
that active is the default type of the interface. In reality, the default
type of the interface can be changed using "passive-interface default"
command. Both "no" and regular commands can be "set" commands, depending
on the default value. They are treated as an "unset" when there's already
a config of the opposite type.
All this logic is in ospf_passive_interface_update.
Fixes#9240.

This code always used double-linked list before this rework in 8.0 that
introduced all these crashes and memory leaks. Using single-linked list
is actually a performance regression, because there are frequent removes
here and single-linked list obviously handles removes much worse.

When bgp_damp_info_free is called from bgp_route.c, we were never
deleting the BDI from the list.
Move the deletion inside bgp_damp_info_free to cover all cases.

Current code is a complete misuse of SLIST structure. Instead of just
adding a SLIST_ENTRY to struct bgp_damp_info, it allocates a separate
structure to be a node in the list.
