Add a new topotest for getting the aigp from the "igp-metric"
for a redistributed route (ospf route in the test).

Fix several issues in sourcing AIGP attribute:
1) AIGP should not be set as default for a redistributed route or a
static network. It should be set by config instead.
2) AIGP sourced by "set aigp-metric igp-metric" in a route-map does
not set the correct value for a redistributed route.
3) When redistribute a connected route like loopback, the AGIP (with
value 0) is sourced by "set aigp-metric igp-metric", but the
attribute is not propagated as the attribute flag is not set.

It happens with FRR using the kernel. During shutdown, the
namespace identifier is attempted to be obtained by zebra, in an
attempt to prepare zebra dataplane nexthop messages.
Fix this by accessing the ns structure.

Fix and adjust the topotest post the fix for route selection with
AIGP.
When there are multiple IGP domains (OSPF in this case), the nexthop
for a BGP route with the AIGP attribute must be resolved in its own
IGP domain.
The changes in r2/bgpd.conf and r3/bgpd.conf are needed as incorrect
IGP metrics are received from NHT for the recursive nexthops. Once
the issue is resolved, the changes can be reverted.

The MT commands are mainly controlled by the binded area, not by interface.
Currently if there is any MT configuration in the area, `metric-style` must
be with the `wide` mode, this requirement is sufficient. So, the
unnecessary/wrong check for MT in the interface should be removed.

A double-free crash happens when a subTLV of the "Router Capability"
TLV is not readable and a previous "Router Capability" TLV was read.
rcap was supposed to be freed later by isis_free_tlvs() ->
free_tlv_router_cap(). In 78774bbcd5 ("isisd: add isis flex-algo lsp
advertisement"), this was not the case because rcap was not saved to
tlvs->router_cap when the function returned early because of a subTLV
length issue.
Always set tlvs->router_cap to free the memory.
Note that this patch has the consequence that in case of subTLV error,
the previously read "Router Capability" subTLVs are kept in memory.
Fixes: 49efc80d34 ("isisd: Ensure rcap is freed in error case")

When an NHRP peer was forwarding a message, it was copying all
extensions from the originally received packet. The authentication
extension must be regenerated hop by hop per RFC2332.
This fix checks for the auth extension when copying extensions
and omits the original packet auth and instead regenerates a new auth extension.
